FEATURES
DESCRIPTION
1
• 2-A Low-Dropout Voltage Regulator
• Available in 1.5 V, 1.8 V, 2.5 V, 3.3 V Fixed
Output and Adjustable Versions
• Open Drain Power-On Reset With 100ms Delay
(TPS752xxQ)
• Open Drain Power-Good (PG) Status Output
(TPS754xxQ)
• Dropout Voltage Typically 210 mV at 2 A
(TPS75233Q)
• Ultralow 75-μA Typical Quiescent Current
• Fast Transient Response
• 2% Tolerance Over Specified Conditions for
Fixed-Output Versions
• 20-Pin TSSOP PowerPAD™ (PWP) Package
• Thermal Shutdown Protection
The TPS752xxQ and TPS754xxQ devices are
low-dropout regulators with integrated power-on reset
and power-good (PG) functions respectively. These
devices are capable of supplying 2 A of output
current with a dropout of 210 mV (TPS75233Q,
TPS75433Q). Quiescent current is 75 μA at full load
and drops down to 1 μA when the device is disabled.
These devices are designed to have fast transient
response for larger load current changes.
23
Because the PMOS device behaves as a low-value
resistor, the dropout voltage is very low (typically
210 mV at an output current of 2 A for the
TPS75x33Q) and is directly proportional to the output
current. Additionally, because the PMOS pass
element is a voltage-driven device, the quiescent
current is very low and independent of output loading
(typically 75 μA over the full range of output current,
1 mA to 2 A). These two key specifications yield a
significant improvement in operating life for
battery-powered systems.
APPLICATIONS
•
•
•
Telecom
Servers
DSP, FPGA Supplies
The device is enabled when EN is connected to a
low-level input voltage. This LDO family also features
a sleep mode; applying a TTL high signal to EN
(enable) shuts down the regulator, reducing the
quiescent current to less than 1 μA at TJ = +25°C.

SLVS242C – MARCH 2000 – REVISED OCTOBER 2007
DESCRIPTION, CONTINUED
The RESET (SVS, POR, or power on reset) output of the TPS752xxQ initiates a reset in microcomputer and
microprocessor systems in the event of an undervoltage condition. An internal comparator in the TPS752xxQ
monitors the output voltage of the regulator to detect an undervoltage condition on the regulated output voltage.
When the output reaches 95% of its regulated voltage, RESET goes to a high-impedance state after a 100-ms
delay. RESET goes to a logic-low state when the regulated output voltage is pulled below 95% (that is, during an
overload condition) of its regulated voltage.
The TPS754xxQ has a power good terminal (PG) as an active high, open drain output for use with a power-on
reset or a low-battery indicator.
The TPS754xxQ and TPS752xxQ are offered in 1.5 V, 1.8 V, 2.5 V and 3.3 V fixed-voltage versions and in an
adjustable version (programmable over the range of 1.5 V to 5 V). Output voltage tolerance is specified as a
maximum of 2% over line, load, and temperature ranges. The TPS754xxQ and TPS752xxQ families are
available in a 20-pin TSSOP (PWP) package.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

SLVS242C – MARCH 2000 – REVISED OCTOBER 2007
APPLICATION INFORMATION
The TPS752xxQ and TPS754xxQ devices include four fixed-output voltage regulators (1.5 V, 1.8 V, 2.5 V and
3.3 V), and an adjustable regulator, the TPS75x01Q (adjustable from 1.5 V to 5 V).
Minimum Load Requirements
The TPS752xxQ and TPS754xxQ families are stable even at zero load; no minimum load is required for
operation.
Pin Functions
Enable (EN)
The EN terminal is an input that enables or shuts down the device. If EN is a logic high, the device is in
shutdown mode. When EN goes to logic low, then the device is enabled.
Power-Good (PG)—TPS754xxQ
The PG terminal is an open drain, active high output that indicates the status of VOUT (output of the LDO). When
VOUT reaches 83% of the regulated voltage, PG goes to a high impedance state. It goes to a low-impedance
state when VOUT falls below 83% (that is, an overload condition) of the regulated voltage. The open drain output
of the PG terminal requires a pullup resistor.
Sense (SENSE)
The SENSE terminal of the fixed output options must be connected to the regulator output, and the connection
should be as short as possible. Internally, SENSE connects to a high-impedance wide-bandwidth amplifier
through a resistor-divider network, and noise pickup feeds through to the regulator output. It is essential to route
the SENSE connection in such a way to minimize/avoid noise pickup. Adding RC networks between the SENSE
terminal and VOUT to filter noise is not recommended because these types of networks may cause the regulator
to oscillate.
Feedback (FB)
FB is an input terminal used for the adjustable-output options and must be connected to an external feedback
resistor divider. The FB connection should be as short as possible. It is essential to route it in such a way to
minimize/avoid noise pickup. Adding RC networks between FB terminal and VOUT to filter noise is not
recommended because these types of networks may cause the regulator to oscillate.
Reset (RESET)—TPS752xxQ
The RESET terminal is an open drain, active low output that indicates the status of VOUT. When VOUT reaches
95% of the regulated voltage, RESET goes to a high-impedance state after a 100-ms delay. RESET goes to a
low-impedance state when VOUT is below 95% of the regulated voltage. The open-drain output of the RESET
terminal requires a pullup resistor.
GND/HEATSINK
All GND/HEATSINK terminals are connected directly to the mount pad for thermal-enhanced operation. These
terminals could be connected to GND or left floating.
Input Capacitor
For a typical application, an input bypass capacitor (0.22 μF to 1 μF) is recommended for device stability. This
capacitor should be as close to the input pins as possible. For fast transient conditions where droop at the input
of the LDO may occur because of high inrush current, it is recommended to place a larger capacitor at the input
as well. The size of this capacitor depends on the output current and response time of the main power supply, as
well as the distance to the load (LDO).

SLVS242C – MARCH 2000 – REVISED OCTOBER 2007
Output Capacitor
As with most LDO regulators, the TPS752xxQ and TPS754xxQ require an output capacitor connected between
OUT and GND to stabilize the internal control loop. The minimum recommended capacitance value is 47 μF and
the ESR (equivalent series resistance) must be between 100 mΩ and 10 Ω. Solid tantalum electrolytic, aluminum
electrolytic, and multilayer ceramic capacitors are all suitable, provided they meet the requirements described in
this section. Larger capacitors provide a wider range of stability and better load transient response.
This information, along with the ESR graphs (see Figure 20 and Figure 21), is included to assist in selection of
suitable capacitance for the user’s application. When necessary to achieve low height requirements along with
high output current and/or high load capacitance, several higher ESR capacitors can be used in parallel to meet
these guidelines.
ESR and Transient Response
LDOs typically require an external output capacitor for stability. In fast transient response applications, capacitors
are used to support the load current while the LDO amplifier is responding. In most applications, one capacitor is
used to support both functions.
Besides its capacitance, every capacitor also contains parasitic impedances. These parasitic impedances are
resistive as well as inductive. The resistive impedance is called equivalent series resistance (ESR), and the
inductive impedance is called equivalent series inductance (ESL). The equivalent schematic diagram of any
capacitor can therefore be drawn as shown in Figure 22.

In most cases one can neglect the effect of inductive impedance ESL. Therefore, the following application
focuses mainly on the parasitic resistance ESR..

SLVS242C – MARCH 2000 – REVISED OCTOBER 2007
In steady state operation (dc state condition), the load current is supplied by the LDO (solid arrow) and the
voltage across the capacitor is the same as the output voltage (V(COUT) = VOUT). This condition means that no
current is flowing into the COUT branch. If IOUT suddenly increases (that is, a transient condition), the following
events occur:
• The LDO is not able to supply the sudden current need because of its response time (t1 in Figure 24).
Therefore, capacitor COUT provides the current for the new load condition (the dashed arrow). COUT now acts
like a battery with an internal resistance, ESR. Depending on the current demand at the output, a voltage
drop occurs at RESR. This voltage is shown as VESR in Figure 23.
• When COUT is conducting current to the load, initial voltage at the load is VOUT = V(COUT) – VESR. As a result
of the discharge of COUT, the output voltage VOUT drops continuously until the response time t1 of the LDO is
reached and the LDO resumes supplying the load. From this point, the output voltage starts rising again until
it reaches the regulated voltage. This period is shown as t2 in Figure 24.
Figure 24 also shows the impact of different ESRs on the output voltage. The left brackets show different levels
of ESRs where number 1 displays the lowest and number 3 displays the highest ESR.
From the above discussion, the following conclusions can be drawn:
• The higher the ESR, the larger the droop at the beginning of load transient.
• The smaller the output capacitor, the faster the discharge time and the bigger the voltage droop during the
LDO response period.
Conclusion
To minimize the transient output droop, capacitors must have a low ESR and be large enough to support the
minimum output voltage requirement.

Programming the TPS75x01Q Adjustable LDO Regulator
The output voltage of the TPS77x01Q adjustable regulator is programmed using an external resistor divider as
shown in Figure 25. The output voltage is calculated using Equation 1:
R
VOUT = Vref ´ (1 + 1 )
R2
(1)
Where:
•
Vref = 1.1834 V typ (the internal reference voltage)
Resistors R1 and R2 should be chosen for approximately 40μA divider current. Lower value resistors can be
used, but offer no inherent advantage and waste more power. Higher values should be avoided as leakage
currents at FB increase the output voltage error. The recommended design procedure is to choose R2 = 30.1 kΩ
to set the divider current at approximately 40μA and then calculate R1 using Equation 2:

R1 = ( OUT - 1) ´ R2

Regulator Protection
The TPS752xxQ and TPS754xxQ PMOS-pass transistors have a built-in back diode that conducts reverse
currents when the input voltage drops below the output voltage (for example, during power down). Current is
conducted from the output to the input and is not internally limited. When extended reverse voltage is anticipated,
external limiting may be appropriate.
The TPS752xxQ and TPS754xxQ also feature internal current limiting and thermal protection. During normal
operation, the TPS752xxQ and TPS754xxQ limit output current to approximately 3.3 A. When current limiting
engages, the output voltage scales back linearly until the overcurrent condition ends. While current limiting is
designed to prevent gross device failure, care should be taken not to exceed the power dissipation ratings of the
package. If the temperature of the device exceeds +150°C (typ), thermal-protection circuitry shuts it down. Once
the device has cooled below +130°C (typ), regulator operation resumes.

Power Dissipation and Junction Temperature
Specified regulator operation is assured to a junction temperature of +125°C; the maximum junction temperature
should be restricted to +125°C under normal operating conditions. This restriction limits the power dissipation the
regulator can handle in any given application. To ensure the junction temperature is within acceptable limits,
calculate the maximum allowable dissipation, PD(max), and the actual dissipation, PD, which must be less than or
equal to PD(max).
The maximum-power-dissipation limit is determined using Equation 3:
TJ(Max) - TA
PD(Max) =
RqJA
(3)
where:
•
•
•
TJ(max) is the maximum allowable junction temperature
RθJA is the thermal resistance junction-to-ambient for the package; that is, 34.6°C/W for the 20-terminal PWP
with no airflow (see Dissipation Ratings Table).
TA is the ambient temperature
The regulator dissipation is calculated using Equation 4:
PD = (VIN - VOUT) ´ IOUT
(4)
Power dissipation resulting from quiescent current is negligible. Excessive power dissipation triggers the thermal
protection circuit.
THERMAL INFORMATION
Thermally-Enhanced TSSOP-20 (PWP–PowerPAD)
The thermally-enhanced PWP package is based on the 20-pin TSSOP, but includes a thermal pad [see
Figure 26(c)] to provide an effective thermal contact between the IC and the printed wiring board (PWB).

Traditionally, surface mount and power have been mutually exclusive terms. A variety of scaled-down
TO220-type packages have leads formed as gull wings to make them applicable for surface-mount applications.
These packages, however, suffer from several shortcomings: they do not address the very low profile
requirements (less than 2 mm) of many of today’s advanced systems, and they do not offer a pin-count high
enough to accommodate increasing integration. On the other hand, traditional low-power surface-mount
packages require power dissipation derating that severely limits the usable range of many high-performance
analog circuits.
The PWP package (a thermally-enhanced TSSOP) combines fine-pitch surface-mount technology with thermal
performance comparable to much larger power packages.

SLVS242C – MARCH 2000 – REVISED OCTOBER 2007
The PWP package is designed to optimize the heat transfer to the PWB. Because of the very small size and
limited mass of a TSSOP package, thermal enhancement is achieved by improving the thermal conduction paths
that remove heat from the component. The thermal pad is formed using a lead-frame design (patent pending)
and manufacturing technique to provide the user with direct connection to the heat-generating IC. When this pad
is soldered or otherwise coupled to an external heat dissipator, high power dissipation in the ultra-thin, fine-pitch,
surface-mount package can be reliably achieved.
Because the conduction path has been enhanced, power-dissipation capability is determined by the thermal
considerations in the PWB design. For example, simply adding a localized copper plane (heatsink surface) that is
coupled to the thermal pad enables the PWP package to dissipate 2.5 W in free air (see Figure 28(a), 8 cm2 of
copper heatsink and natural convection). Increasing the heatsink size increases the power dissipation range for
the component. The power dissipation limit can be further improved by adding airflow to a PWB/IC assembly
(see Figure 27 and Figure 28). The line drawn at 0.3 cm2 in Figure 27 and Figure 28 indicates performance at
the minimum recommended heatsink size, illustrated in Figure 30.
The thermal pad is directly connected to the substrate of the IC, which for the TPS752xxQPWP and
TPS754xxQPWP series is a secondary electrical connection to device ground. The heat-sink surface that is
added to the PWP can be a ground plane or left electrically isolated. In TO220-type surface-mount packages, the
thermal connection is also the primary electrical connection for a given terminal which is not always ground. The
PWP package provides up to 16 independent leads that can be used as inputs and outputs. (Note: leads 1, 10,
11, and 20 are internally connected to the thermal pad and the IC substrate.)

Figure 29 is an example of a thermally-enhanced PWB layout for use with the new PWP package. This board
configuration was used in the thermal experiments that generated the power ratings shown in Figure 27 and
Figure 28. As discussed earlier, copper has been added on the PWB to conduct heat away from the device. RθJA
for this assembly is illustrated in Figure 27 as a function of heatsink area. A family of curves is included to
illustrate the effect of airflow introduced into the system.

Figure 29. PWB Layout (Including Copper Heatsink Area) for Thermally-Enhanced PWP Package
From Figure 27, RθJA for a PWB assembly can be determined and used to calculate the maximum
power-dissipation limit for the component/PWB assembly, with the equation:
TJ(Max) - TA
PD(Max) =
RqJA (System)
(5)
Where TJmax is the maximum specified junction temperature (+150°C absolute maximum limit, +125°C
recommended operating limit) and TA is the ambient temperature.
PD(max) should then be applied to the internal power dissipated by the TPS75433QPWP regulator. The equation
for calculating total internal power dissipation of the TPS75433QPWP is:
PD(total) = (VIN - VOUT) ´ IOUT + VIN ´ IQ
(6)
Because the quiescent current of the TPS75433QPWP is very low, the second term is negligible, further
simplifying the equation to:
PD(total) = (VIN - VOUT) ´ IOUT
(7)
For the case where TA = +55°C, airflow = 200 ft/min, copper heat-sink area = 4 cm2, the maximum
power-dissipation limit can be calculated. First, from Figure 27, we find the system RθJA is 50°C/W; therefore, the
maximum power-dissipation limit is:
TJ(Max) - TA 125°C - 55°C
=
= 1.4 W
PD(Max) =
RqJA (System)
50°C/W
(8)
If the system implements a TPS75433QPWP regulator, where VIN = 5 V and IOUT = 800 mA, the internal power
dissipation is:
PD(total) = (VIN - VOUT) ´ IOUT = (5 - 3.3) ´ 0.8 = 1.36 W
(9)
Comparing PD(total) with PD(max) reveals that the power dissipation in this example does not exceed the calculated
limit. When it does, one of two corrective actions should be made: either raise the power-dissipation limit by
increasing the airflow or the heat-sink area, or loweri the internal power dissipation of the regulator by reducing
the input voltage or the load current. In either case, the above calculations should be repeated with the new
system parameters.

Mounting Information
The primary requirement is to complete the thermal contact between the thermal pad and the PWB metal. The
thermal pad is a solderable surface and is fully intended to be soldered at the time the component is mounted.
Although voiding in the thermal-pad solder-connection is not desirable, up to 50% voiding is acceptable. The data
included in Figure 27 and Figure 28 are for soldered connections with voiding between 20% and 50%. The
thermal analysis shows no significant difference resulting from the variation in voiding percentage.
Figure 30 shows the solder-mask land pattern for the PWP package. The minimum recommended heat-sink area
is also illustrated. This is simply a copper plane under the body extent of the package, including metal routed
under terminals 1, 10, 11, and 20.

information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve 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. 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.
