3 Description

The LP5907-Q1 is a low-noise LDO that can supply

250 mA of output current. Designed to meet the

requirements of RF and analog circuits, the LP5907-

Q1 provides low noise, high PSRR, low quiescent

current, and low line or load transient response

figures. Using new innovative design techniques, the

LP5907-Q1 offers class-leading noise performance

without a noise bypass capacitor and the ability for

remote output capacitor placement.

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

a 1-μF output ceramic capacitor (no separate noise

bypass capacitor is required).

This device is available with fixed output voltages

from 1.2 V to 4.5 V in 25-mV steps. Contact Texas

Instruments Sales for specific voltage option needs.
