3 Description

The LP5912-Q1 is low-noise LDO that can supply up

to 500 mA of output current. Designed to meet the

requirements of RF and analog circuits, the LP5912-

Q1 device provides low noise, high PSRR, low

quiescent current, and low line and load transient

response. The LP5912-Q1 offers class-leading noise

performance without a noise bypass capacitor and

with

the

ability

for

remote

output

capacitance

placement.

The device is designed to work with a 1-µF input and

a 1-µF output ceramic capacitor (no separate noise

bypass capacitor required).

This device is available with fixed output voltages

from 0.8 V to 5.5 V in 25-mV steps. Contact Texas

Instruments Sales for specific voltage option needs.
