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.

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. 7.2 Functional Block Diagram OUT IN POR EN EN + RF CF + VBG 1.20V RAD EN + EN EN 1 M VIH GND 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. Submit Documentation Feedback Copyright © 2012–2015, Texas Instruments Incorporated Product Folder Links: LP5907 11 LP5907 SNVS798I – APRIL 2012 – REVISED AUGUST 2015 www.ti.com 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 Thermal Shutdown 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) pull-down 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). 12 Submit Documentation Feedback Copyright © 2012–2015, Texas Instruments Incorporated Product Folder Links: LP5907 LP5907 www.ti.com SNVS798I – APRIL 2012 – REVISED AUGUST 2015 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. INPUT IN 1 PF ENABLE OUT LP5907 OUTPUT 1 PF EN GND GND Figure 21.

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. 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) Submit Documentation Feedback Copyright © 2012–2015, Texas Instruments Incorporated Product Folder Links: LP5907 13 LP5907 SNVS798I – APRIL 2012 – REVISED AUGUST 2015 www.ti.com 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. Important: 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, then it is recommended to increase the input capacitor to at least 10 µF. Also, tantalum capacitors can suffer catastrophic failures due to surge current when connected to a low-impedance source of power (like a battery or a very large capacitor). If a tantalum capacitor is used at the input, it must 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). 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. 14 Submit Documentation Feedback Copyright © 2012–2015, Texas Instruments Incorporated Product Folder Links: LP5907 LP5907 www.ti.com SNVS798I – APRIL 2012 – REVISED AUGUST 2015 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, it is good to 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 as possible to ground layer 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 pull-down 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 pull-down 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 turn-on/off voltage thresholds listed in the Electrical Characteristics under VIL and VIH.

The input supply should 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 should be at least VOUT + 1 V.

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 as is practical to the package. The ground connections for CIN and COUT should be back to the LP5907 ground pin using as wide, and as short, of a copper trace as is practical. Connections using long trace lengths, narrow trace widths, and/or connections through vias should be avoided. These will add parasitic inductances and resistance that results in inferior performance especially during transient conditions 10.2 Layout Examples VIN VOUT CIN 1 IN 2 GND 3 EN 5 OUT COUT GND Enable GND 4 N/C Figure 24.

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. 18 Submit Documentation Feedback Copyright © 2012–2015, Texas Instruments Incorporated Product Folder Links: LP5907 LP5907 www.ti.com SNVS798I – APRIL 2012 – REVISED AUGUST 2015 11 Device and Documentation Support 11.1 Documentation Support 11.1.1 Related Documentation For related documentation, see the following: Texas Instruments Application Note AN-1112 DSBGA Wafer Level Chip Scale Package (SNVA009).

Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment. TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily performed. TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide adequate design and operating safeguards. TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or endorsement thereof. Use of such information 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. Reproduction of significant portions of TI information in TI data books or 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 altered documentation. Information of third parties may be subject to additional restrictions. Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements. Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use of any TI components in safety-critical applications. In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and requirements. Nonetheless, such components are subject to these terms. No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties have executed a special agreement specifically governing such use. Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and regulatory requirements in connection with such use. TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
