description

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 1.8-V, 2.7-V, 2.8-V and 3.3-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.

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.

This document contains information on products in more than one phase

of development. The status of each device is indicated on the page(s)

specifying its electrical characteristics.
