3 Description

The TPS794 low-dropout (LDO) linear voltage

regulator features high power-supply rejection ratio

(PSRR), low-noise, fast start-up, and excellent line

and load transient responses. Each device in the

family is stable with a small 2.2μF ceramic capacitor

on the output. The TPS794 offers low dropout

voltages, 155mV (typ) at 250mA.Applications with

analog components that are noise-sensitive, such as

portable RF electronics, benefit from the high PSRR

and low noise features as well as the fast response

time.
