Regulated output voltage. A minimum 1-μF low-ESR capacitor should be
connected to this pin. Connect this output to the load circuit. An internal
230-Ω (typical) pulldown resistor prevents a charge remaining on VOUT
when the regulator is in the shutdown mode (VEN low).
Enable input. A low voltage (< VIL) on this pin turns the regulator off and
discharges the output pin to GND through an internal 230-Ω pulldown
resistor. A high voltage (> VIH) on this pin enables the regulator output.
This pin has an internal 1M-Ω pulldown resistor to hold the regulator off
by default.

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating
Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
All voltages are with respect to the GND pin.
In applications where high power dissipation and/or poor package thermal resistance is present, the maximum ambient temperature may
have to be derated. Maximum ambient temperature (TA-MAX) is dependent on the maximum operating junction temperature (TJ-MAX-OP =
125°C), the maximum power dissipation of the device in the application (PD-MAX), and the junction-to ambient thermal resistance of the
part/package in the application (RθJA), as given by the following equation: TA-MAX = TJ-MAX-OP – (RθJA × PD-MAX). See Applications and
Implementation.

All voltages are with respect to the device GND terminal, unless otherwise stated.
Minimum and maximum limits are ensured through test, design, or statistical correlation over the junction temperature (TJ) range of
–40°C to 125°C, unless otherwise stated. Typical values represent the most likely parametric norm at TA = 25°C, and are provided for
reference purposes only.
In applications where high power dissipation and/or poor package thermal resistance is present, the maximum ambient temperature may
have to be derated. Maximum ambient temperature (TA-MAX) is dependent on the maximum operating junction temperature (TJ-MAX-OP =
125°C), the maximum power dissipation of the device in the application (PD-MAX), and the junction-to ambient thermal resistance of the
part/package in the application RθJA), as given by the following equation: TA-MAX = TJ-MAX-OP – (RθJA × PD-MAX). See Applications and
Implementation.
The device maintains a stable, regulated output voltage without a load current.
Quiescent current is defined here as the difference in current between the input voltage source and the load at VOUT.
Ground current is defined here as the total current flowing to ground as a result of all input voltages applied to the device.
Dropout voltage is the voltage difference between the input and the output at which the output voltage drops to 100 mV below its
nominal value.
Short-circuit current (ISC) for the LP5907 is equivalent to current limit. To minimize thermal effects during testing, ISC is measured with
VOUT pulled to 100 mV below its nominal voltage.
This specification is verified by design.

The minimum capacitance should be greater than 0.5 μF over the full range of operating conditions. The capacitor tolerance should be
30% or better over the full temperature range. The full range of operating conditions for the capacitor in the application must be
considered during device selection to ensure this minimum capacitance specification is met. X7R capacitors are recommended however
capacitor types X5R, Y5V and Z5U may be used with consideration of the application and conditions.
This specification is verified by design.

7 Detailed Description
7.1 Overview
Designed to meet the needs of sensitive RF and analog circuits, the LP5907 provides low noise, high PSRR, low
quiescent current, as well as low line and load transient response figures. Using new innovative design
techniques, the LP5907 offers class leading noise performance without the need for a separate noise filter
capacitor.
The LP5907 is designed to perform with a single 1-µF input capacitor and a single 1-µF ceramic output
capacitor. With a reasonable PCB layout, the single 1-µF ceramic output capacitor can be placed up to 10 cm
away from the LP5907 device.

7.3 Feature Description
7.3.1 Enable (EN)
The LP5907 EN pin is internally held low by a 1-MΩ resistor to GND. The EN pin voltage must be higher than the
VIH threshold to ensure that the device is fully enabled under all operating conditions. The EN pin voltage must
be lower than the VIL threshold to ensure that the device is fully disabled and the automatic output discharge is
activated.
7.3.2 Low Output Noise
Any internal noise at the LP5907 reference voltage is reduced by a first order low-pass RC filter before it is
passed to the output buffer stage. The low-pass RC filter has a –3 dB cut-off frequency of approximately 0.1 Hz.

Feature Description (continued)
7.3.3 Output Automatic Discharge
The LP5907 output employs an internal 230-Ω (typical) pulldown resistance to discharge the output when the EN
pin is low, and the device is disabled.
7.3.4 Remote Output Capacitor Placement
The LP5907 requires at least a 1-µF capacitor at the OUT pin, but there are no strict requirements about the
location of the capacitor in regards the OUT pin. In practical designs, the output capacitor may be located up to
10 cm away from the LDO.
7.3.5 Thermal Overload Protection (TSD)
Thermal shutdown disables the output when the junction temperature rises to approximately 160°C which allows
the device to cool. When the junction temperature cools to approximately 145°C, the output circuitry enables.
Based on power dissipation, thermal resistance, and ambient temperature, the thermal protection circuit may
cycle on and off. This thermal cycling limits the dissipation of the regulator and protects it from damage as a
result of overheating.
The thermal shutdown circuitry of the LP5907 has been designed to protect against temporary thermal overload
conditions. The TSD circuitry was not intended to replace proper heat-sinking. Continuously running the LP5907
device into thermal shutdown may degrade device reliability.
7.4 Device Functional Modes
7.4.1 Enable (EN)
The LP5907 Enable (EN) pin is internally held low by a 1-MΩ resistor to GND. The EN pin voltage must be
higher than the VIH threshold to ensure that the device is fully enabled under all operating conditions.
When the EN pin is pulled low, and the output is disabled, the output automatic discharge circuitry is activated.
Any charge on the OUT pin is discharged to GND through the internal 230-Ω (typical) pulldown resistance.
7.4.2 Minimum Operating Input Voltage (VIN)
The LP5907 does not include any dedicated UVLO circuitry. The LP5907 internal circuitry is not fully functional
until VIN is at least 2.2 V. The output voltage is not regulated until VIN has reached at least the greater of 2.2 V or
(VOUT + VDO).

8 Applications and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
8.1 Application Information
The LP5907 is designed to meet the requirements of RF and analog circuits, by providing low noise, high PSRR,
low quiescent current, and low line or load transient response figures. The device offers excellent noise
performance without the need for a noise bypass capacitor and is stable with input and output capacitors with a
value of 1 µF. The LP5907 delivers this performance in industry standard packages such as DSBGA, X2SON,
and SOT-23 which, for this device, are specified with an operating junction temperature (TJ) of –40°C to 125°C.
8.2 Typical Application
Figure 21 shows the typical application circuit for the LP5907. Input and output capacitances may need to be
increased above the 1 µF minimum for some applications.

8.2.2 Detailed Design Procedure
8.2.2.1 Power Dissipation and Device Operation
The permissible power dissipation for any package is a measure of the capability of the device to pass heat from
the power source, the junctions of the IC, to the ultimate heat sink, the ambient environment. Thus, the power
dissipation is dependent on the ambient temperature and the thermal resistance across the various interfaces
between the die junction and ambient air.

LP5907
SNVS798L – APRIL 2012 – REVISED SEPTEMBER 2016
www.ti.com
The maximum allowable power dissipation for the device in a given package can be calculated using Equation 1:
PD-MAX = ((TJ-MAX – TA) / RθJA)
(1)
The actual power being dissipated in the device can be represented by Equation 2:
PD = (VIN – VOUT) × IOUT
(2)
These two equations establish the relationship between the maximum power dissipation allowed due to thermal
consideration, the voltage drop across the device, and the continuous current capability of the device. These two
equations should be used to determine the optimum operating conditions for the device in the application.
In applications where lower power dissipation (PD) and/or excellent package thermal resistance (RθJA) is present,
the maximum ambient temperature (TA-MAX) may be increased.
In applications where high power dissipation and/or poor package thermal resistance is present, the maximum
ambient temperature (TA-MAX) may have to be derated. TA-MAX is dependent on the maximum operating junction
temperature (TJ-MAX-OP = 125°C), the maximum allowable power dissipation in the device package in the
application (PD-MAX), and the junction-to ambient thermal resistance of the part/package in the application (RθJA),
as given by Equation 3:
TA-MAX = (TJ-MAX-OP – (RθJA × PD-MAX))
(3)
Alternately, if TA-MAX can not be derated, the PD value must be reduced. This can be accomplished by reducing
VIN in the VIN–VOUT term as long as the minimum VIN is met, or by reducing the IOUT term, or by some
combination of the two.
8.2.2.2 External Capacitors
Like most low-dropout regulators, the LP5907 requires external capacitors for regulator stability. The device is
specifically designed for portable applications requiring minimum board space and smallest components. These
capacitors must be correctly selected for good performance.
8.2.2.3 Input Capacitor
An input capacitor is required for stability. The input capacitor should be at least equal to, or greater than, the
output capacitor for good load transient performance. At least a 1 µF capacitor has to be connected between the
LP5907 input pin and ground for stable operation over full load current range. Basically, it is ok to have more
output capacitance than input, as long as the input is at least 1 µF.
The input capacitor must be located a distance of not more than 1 cm from the input pin and returned to a clean
analog ground. Any good quality ceramic, tantalum, or film capacitor may be used at the input.
NOTE
To ensure stable operation it is essential that good PCB practices are employed to
minimize ground impedance and keep input inductance low. If these conditions cannot be
met, or if long leads are to be used to connect the battery or other power source to the
LP5907, TI recommends increasing the input capacitor to at least 10 µF. Also, tantalum
capacitors can suffer catastrophic failures due to surge current when connected to a lowimpedance source of power (like a battery or a very large capacitor). If a tantalum
capacitor is used at the input, it should be verified by the manufacturer to have a surge
current rating sufficient for the application. The initial tolerance, applied voltage de-rating,
and temperature coefficient must all be considered when selecting the input capacitor to
ensure the actual capacitance is never less than 0.7 µF over the entire operating range.
8.2.2.4 Output Capacitor
The LP5907 is designed specifically to work with a very small ceramic output capacitor, typically 1 µF. A ceramic
capacitor (dielectric types X5R or X7R) in the 1 µF to 10 µF range, and with ESR between 5 mΩ to 500 mΩ, is
suitable in the LP5907 application circuit. For this device the output capacitor should be connected between the
OUT pin and a good connection back to the GND pin.
It may also be possible to use tantalum or film capacitors at the device output, VOUT, but these are not as
attractive for reasons of size and cost (see Capacitor Characteristics).

www.ti.com
SNVS798L – APRIL 2012 – REVISED SEPTEMBER 2016
The output capacitor must meet the requirement for the minimum value of capacitance and have an ESR value
that is within the range 5 mΩ to 500 mΩ for stability. Like the input capacitor, the initial tolerance, applied voltage
de-rating, and temperature coefficient must all be considered when selecting the input capacitor to ensure the
actual capacitance is never less than 0.7 µF over the entire operating range.
8.2.2.5 Capacitor Characteristics
The LP5907 is designed to work with ceramic capacitors on the input and output to take advantage of the
benefits they offer. For capacitance values in the range of 1 µF to 10 µF, ceramic capacitors are the smallest,
least expensive and have the lowest ESR values, thus making them best for eliminating high frequency noise.
The ESR of a typical 1 µF ceramic capacitor is in the range of 20 mΩ to 40 mΩ, which easily meets the ESR
requirement for stability for the LP5907.
A better choice for temperature coefficient in a ceramic capacitor is X7R. This type of capacitor is the most stable
and holds the capacitance within ±15% over the temperature range. Tantalum capacitors are less desirable than
ceramic for use as output capacitors because they are more expensive when comparing equivalent capacitance
and voltage ratings in the 1 µF to 10 µF range.
Another important consideration is that tantalum capacitors have higher ESR values than equivalent size
ceramics. This means that while it may be possible to find a tantalum capacitor with an ESR value within the
stable range, it would have to be larger in capacitance (which means bigger and more costly) than a ceramic
capacitor with the same ESR value. It should also be noted that the ESR of a typical tantalum increases about
2:1 as the temperature goes from 25°C down to –40°C, so some guard band must be allowed.
8.2.2.6 Remote Capacitor Operation
The LP5907 requires at least a 1-µF capacitor at the OUT pin, but there is no strict requirements about the
location of the capacitor in regards to the pin. In practical designs the output capacitor may be located up to 10
cm away from the LDO. This means that there is no need to have a special capacitor close to the output pin if
there is already respective capacitors in the system (like a capacitor at the input of supplied part). The remote
capacitor feature helps user to minimize the number of capacitors in the system.
As a good design practice, keep the wiring parasitic inductance at a minimum, which means to use as wide as
possible traces from the LDO output to the capacitors, keeping the LDO output trace layer as close to ground
layer as possible and avoiding vias on the path. If there is a need to use vias, implement as many as possible
vias between the connection layers. The recommendation is to keep parasitic wiring inductance less than 35 nH.
For the applications with fast load transients, it is recommended to use an input capacitor equal to or larger to
the sum of the capacitance at the output node for the best load transient performance.
8.2.2.7 No-Load Stability
The LP5907 remains stable, and in regulation, with no external load.
8.2.2.8 Enable Control
The LP5907 may be switched ON or OFF by a logic input at the EN pin. A voltage on this pin greater than VIH
turns the device on, while a voltage less than VIL turns the device off.
When the EN pin is low, the regulator output is off and the device typically consumes less than 1 µA.
Additionally, an output pulldown circuit is activated which ensures that any charge stored on COUT is discharged
to ground.
If the application does not require the use of the shutdown feature, the EN pin can be tied directly to the IN pin to
keep the regulator output permanently on.
An internal 1-MΩ pulldown resistor ties the EN input to ground, ensuring that the device remains off if the EN pin
is left open circuit. To ensure proper operation, the signal source used to drive the EN pin must be able to swing
above and below the specified turnon or turnoff voltage thresholds listed in the Electrical Characteristics under
VIL and VIH.

9 Power Supply Recommendations
This device is designed to operate from an input supply voltage range of 2.2 V to 5.5 V. The input supply must
be well regulated and free of spurious noise. To ensure that the LP5907 output voltage is well regulated and
dynamic performance is optimum, the input supply must be at least VOUT + 1 V. A minimum capacitor value of 1
µF is required to be within 1 cm of the IN pin.

10 Layout
10.1 Layout Guidelines
The dynamic performance of the LP5907 is dependant on the layout of the PCB. PCB layout practices that are
adequate for typical LDOs may degrade the PSRR, noise, or transient performance of the LP5907.
Best performance is achieved by placing CIN and COUT on the same side of the PCB as the LP5907, and as
close to the package as is practical. The ground connections for CIN and COUT must be back to the LP5907
ground pin using as wide and short a copper trace as is practical.
Connections using long trace lengths, narrow trace widths, and/or connections through vias must be avoided.
These add parasitic inductances and resistance that results in inferior performance especially during transient
conditions

10.3 X2SON Mounting
The X2SON package thermal pad must be soldered to the printed circuit board for proper thermal and
mechanical performance. For more information, see the Application Report QFN/SON PCB Attachment
(SLUA271).
10.4 DSBGA Mounting
The DSBGA package requires specific mounting techniques, which are detailed in AN-1112 DSBGA Wafer Level
Chip Scale Package (SNVA009). For best results during assembly, alignment ordinals on the PC board may be
used to facilitate placement of the DSBGA device.
10.5 DSBGA Light Sensitivity
Exposing the DSBGA device to direct light may cause incorrect operation of the device. Light sources such as
halogen lamps can affect electrical performance if they are situated in proximity to the device. Light with
wavelengths in the red and infrared part of the spectrum have the most detrimental effect; thus, the fluorescent
lighting used inside most buildings has very little effect on performance.

RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance
do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may
reference these types of products as "Pb-Free".
RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based
flame retardants must also meet the <=1000ppm threshold requirement.
(3)
MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
(4)
There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.
(5)
Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation
of the previous line and the two combined represent the entire Device Marking for that device.
(6)
Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish
value exceeds the maximum column width.

IMPORTANT NOTICE
Texas Instruments Incorporated (TI) reserves the right to make corrections, enhancements, improvements and other changes to its
semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest issue. Buyers
should obtain the latest relevant information before placing orders and should verify that such information is current and complete.
TI’s published terms of sale for semiconductor products (http://www.ti.com/sc/docs/stdterms.htm) apply to the sale of packaged integrated
circuit products that TI has qualified and released to market. Additional terms may apply to the use or sale of other types of TI products and
services.
Reproduction of significant portions of TI information in TI data sheets is permissible only if reproduction is without alteration and is
accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such reproduced
documentation. Information of third parties may be subject to additional restrictions. Resale of TI products or services with statements
different from or beyond the parameters stated by TI for that product or service voids all express and any implied warranties for the
associated TI product or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements.
Buyers and others who are developing systems that incorporate TI products (collectively, “Designers”) understand and agree that Designers
remain responsible for using their independent analysis, evaluation and judgment in designing their applications and that Designers have
full and exclusive responsibility to assure the safety of Designers' applications and compliance of their applications (and of all TI products
used in or for Designers’ applications) with all applicable regulations, laws and other applicable requirements. Designer represents that, with
respect to their applications, Designer has all the necessary expertise to create and implement safeguards that (1) anticipate dangerous
consequences of failures, (2) monitor failures and their consequences, and (3) lessen the likelihood of failures that might cause harm and
take appropriate actions. Designer agrees that prior to using or distributing any applications that include TI products, Designer will
thoroughly test such applications and the functionality of such TI products as used in such applications.
TI’s provision of technical, application or other design advice, quality characterization, reliability data or other services or information,
including, but not limited to, reference designs and materials relating to evaluation modules, (collectively, “TI Resources”) are intended to
assist designers who are developing applications that incorporate TI products; by downloading, accessing or using TI Resources in any
way, Designer (individually or, if Designer is acting on behalf of a company, Designer’s company) agrees to use any particular TI Resource
solely for this purpose and subject to the terms of this Notice.
TI’s provision of TI Resources does not expand or otherwise alter TI’s applicable published warranties or warranty disclaimers for TI
products, and no additional obligations or liabilities arise from TI providing such TI Resources. TI reserves the right to make corrections,
enhancements, improvements and other changes to its TI Resources. TI has not conducted any testing other than that specifically
described in the published documentation for a particular TI Resource.
Designer is authorized to use, copy and modify any individual TI Resource only in connection with the development of applications that
include the TI product(s) identified in such TI Resource. NO OTHER LICENSE, EXPRESS OR IMPLIED, BY ESTOPPEL OR OTHERWISE
TO ANY OTHER TI INTELLECTUAL PROPERTY RIGHT, AND NO LICENSE TO ANY TECHNOLOGY OR INTELLECTUAL PROPERTY
RIGHT OF TI OR ANY THIRD PARTY IS GRANTED HEREIN, including but not limited to any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information
regarding or referencing third-party products or services does not constitute a license to use such products or services, or a warranty or
endorsement thereof. Use of TI Resources may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
TI RESOURCES ARE PROVIDED “AS IS” AND WITH ALL FAULTS. TI DISCLAIMS ALL OTHER WARRANTIES OR
REPRESENTATIONS, EXPRESS OR IMPLIED, REGARDING RESOURCES OR USE THEREOF, INCLUDING BUT NOT LIMITED TO
ACCURACY OR COMPLETENESS, TITLE, ANY EPIDEMIC FAILURE WARRANTY AND ANY IMPLIED WARRANTIES OF
MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT OF ANY THIRD PARTY INTELLECTUAL
PROPERTY RIGHTS. TI SHALL NOT BE LIABLE FOR AND SHALL NOT DEFEND OR INDEMNIFY DESIGNER AGAINST ANY CLAIM,
INCLUDING BUT NOT LIMITED TO ANY INFRINGEMENT CLAIM THAT RELATES TO OR IS BASED ON ANY COMBINATION OF
PRODUCTS EVEN IF DESCRIBED IN TI RESOURCES OR OTHERWISE. IN NO EVENT SHALL TI BE LIABLE FOR ANY ACTUAL,
DIRECT, SPECIAL, COLLATERAL, INDIRECT, PUNITIVE, INCIDENTAL, CONSEQUENTIAL OR EXEMPLARY DAMAGES IN
CONNECTION WITH OR ARISING OUT OF TI RESOURCES OR USE THEREOF, AND REGARDLESS OF WHETHER TI HAS BEEN
ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
Unless TI has explicitly designated an individual product as meeting the requirements of a particular industry standard (e.g., ISO/TS 16949
and ISO 26262), TI is not responsible for any failure to meet such industry standard requirements.
Where TI specifically promotes products as facilitating functional safety or as compliant with industry functional safety standards, such
products are intended to help enable customers to design and create their own applications that meet applicable functional safety standards
and requirements. Using products in an application does not by itself establish any safety features in the application. Designers must
ensure compliance with safety-related requirements and standards applicable to their applications. Designer may not use any TI products in
life-critical medical equipment unless authorized officers of the parties have executed a special contract specifically governing such use.
Life-critical medical equipment is medical equipment where failure of such equipment would cause serious bodily injury or death (e.g., life
support, pacemakers, defibrillators, heart pumps, neurostimulators, and implantables). Such equipment includes, without limitation, all
medical devices identified by the U.S. Food and Drug Administration as Class III devices and equivalent classifications outside the U.S.
TI may expressly designate certain products as completing a particular qualification (e.g., Q100, Military Grade, or Enhanced Product).
Designers agree that it has the necessary expertise to select the product with the appropriate qualification designation for their applications
and that proper product selection is at Designers’ own risk. Designers are solely responsible for compliance with all legal and regulatory
requirements in connection with such selection.
Designer will fully indemnify TI and its representatives against any damages, costs, losses, and/or liabilities arising out of Designer’s noncompliance with the terms and provisions of this Notice.
