= 250 mA

The TPS773xx and TPS774xx are low-dropout

regulators with integrated power-on reset and

power good (PG) function respectively. These

devicesarecapableofsupplying250mAofoutput

current with a dropout of 200 mV (TPS77333,

TPS77433). 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.

TPS773xx and TPS774xx are designed to have

fast transient response for larger load current

changes.

The TPS773xx or TPS774xx 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 TPS773xx and TPS774xx families are available in 8-pin MSOP (DGK)

packages.
