3 Description

The TPS796-Q1 low-dropout (LDO), low-power, linear

voltage regulator features high power-supply rejection

ratio (PSRR), ultra-low-noise, fast start-up, and

excellent line and load transient responses. This

device is stable with a small 1μF ceramic capacitor

on the output.

The low output noise and great PSRR performance

make the device designed to power-sensitive analog

loads. The TPS796-Q1 is a flexible device for post

regulation because this device supports an input

voltage range from 2.7V to 5.5V.
