3 Description

The LP5907 is a low-noise LDO that can supply

up to 250mA output current. Designed to meet the

requirements of RF and analog circuits, the LP5907

provides low noise, high PSRR, low quiescent current,

and low line or load transient response figures. Using

innovative design techniques, the LP5907 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 1µF input and

a 1µF output ceramic capacitor (no separate noise

bypass capacitor is required).

This device is available with fixed output voltages

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

Instruments Sales for specific voltage option needs.
