The TPS771xx and TPS772xx are low-dropout
regulators with integrated power-on reset and
power good (PG) function respectively. These
devicesarecapableofsupplying150mAofoutput
current with a dropout of 115 mV (TPS77133,
TPS77233). Quiescent current is 92 µA at full load
dropping down to 1 µA when device is disabled.
These devices are optimized to be stable with a
wide range of output capacitors including lowESR
ceramic (10 µF) or low capacitance (1 µF)
tantalum capacitors. These devices have ex-

The TPS771xx or TPS772xx is offered in 1.5 V,
1.8-V, 2.7-V, 2.8-V, 3.3-V, and 5.0 V fixed-voltage versions and in an adjustable version (programmable over
the range of 1.5 V to 5.5 V). Output voltage tolerance is 2% over line, load, and temperature ranges. The
TPS771xx and TPS772xx families are available in 8-pin MSOP (DGK) packages.
Because the PMOS device behaves as a low-value resistor, the dropout voltage is very low (typically 115 mV
at an output current of 150 mA for 3.3 volt option) and is directly proportional to the output current. Additionally,
since the PMOS pass element is a voltage-driven device, the quiescent current is very low and independent
of output loading (typically 92 µA over the full range of output current, 0 mA to 150 mA). These two key
specifications yield a significant improvement in operating life for battery-powered systems.

description (continued)
The device is enabled when the EN pin 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 T = 25°C.
J
The TPS771xx features an integrated power-on reset, commonly used as a supply voltage supervisor (SVS)
or reset output voltage. The RESET output of the TPS771xx initiates a reset in DSP, microcomputer or
microprocessor systems at power up and in the event of an undervoltage condition. An internal comparator in
the TPS771xx monitors the output voltage of the regulator to detect an undervoltage condition on the regulated
output voltage. When OUT reaches 95% of its regulated voltage, RESET will go to a high-impedance state after
a 220 ms delay. RESET will go to low-impedance state when OUT is pulled below 95% (i.e. over load condition)
of its regulated voltage.
For the TPS772xx, the power good terminal (PG) is an active high output, which can be used to implement a
power-on reset or a low-battery indicator. An internal comparator in the TPS772xx monitors the output voltage
of the regulator to detect an undervoltage condition on the regulated output voltage. When OUTfalls below 82%
of its regulated voltage, PG will go to a low-impedance state. PG will go to a high-impedance state when OUT
is above 82% of its regulated voltage.

enable (EN)
The EN terminal is an input which enables or shuts down the device. If EN is a logic high, the device will be in
shutdown mode. When EN goes to logic low, then the device will be enabled.
power good (PG) (TPS772xx)
The PG terminal is an open drain, active high output that indicates the status of V (output of the LDO). When
out
V
reaches 82% of the regulated voltage, PG will go to a high-impedance state. It will go to a low-impedance
out
state when V falls below 82% (i.e. over load condition) of the regulated voltage. The open drain output of the
out
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 V to filter noise is not recommended because it 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 V

external capacitor requirements
An input capacitor is not usually required; however, a bypass capacitor (0.047 µF or larger) improves load
transient response and noise rejection if the TPS771xx or TPS772xx is located more than a few inches from
the power supply. A higher-capacitance capacitor may be necessary if large (hundreds of milliamps) load
transients with fast rise times are anticipated.
Most low noise LDOs require an external capacitor to further reduce noise. This will impact the cost and board
space. TheTPS771xxandTPS772xxhaveverylownoisespecificationrequirementswithoutusinganyexternal
components.
Like all low dropout regulators, the TPS771xx or TPS772xx requires an output capacitor connected between
OUT (output of the LDO) and GND (signal ground) to stabilize the internal control loop. The minimum
recommended capacitance value is 1 µF provided the ESR meets the requirement in Figures 19 and 21. In
addition, a low-ESR capacitor can be used if the capacitance is at least 10 µF and the ESR meets the
requirements in Figures 18 and 20. Solid tantalum electrolytic, aluminum electrolytic, and multilayer ceramic
capacitors are all suitable, provided they meet the requirements described previously.
Ceramic capacitors have different types of dielectric material with each exhibiting different temperature and
voltage variation. The most common types are X5R, X7R, Y5U, Z5U, and NPO. The NPO type ceramic type
capacitors are generally the most stable over temperature. However, the X5R and X7R are also relatively stable
over temperature (with the X7R being the more stable of the two) and are therefore acceptable to use. The Y5U
and Z5U types provide high capacitance in a small geometry, but exhibit large variations over temperature;
therefore, the Y5U and Z5U are not generally recommended for use on this LDO. Independent of which type
of capacitor is used, one must make certain that at the worst case condition the capacitance/ESR meets the
requirement specified in Figures 18 – 21.

From above, 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

APPLICATION INFORMATION
regulator protection
The TPS771xx or TPS772xx PMOS-pass transistor has a built-in back diode that conducts reverse currents
when the input voltage drops below the output voltage (e.g., 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 TPS771xx or TPS772xx also features internal current limiting and thermal protection. During normal
operation, the TPS771xx or TPS772xx limits output current to approximately 0.9 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, P
, and the actual dissipation, P , which must be less than
D(max)
D
or equal to P
.
D(max)
The maximum-power-dissipation limit is determined using the following equation:

Power dissipation resulting from quiescent current is negligible. Excessive power dissipation will trigger the
