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-

without using any added filter capacitors.

TPS771xx and TPS772xx are designed to have

fast transient response for larger load current

changes.

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.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of Texas Instruments

standard warranty. Production processing does not necessarily include

testing of all parameters.
