LP5907

Ultra Low-Noise, 250 mA Linear Regulator for RF/Analog

Circuits - Requires No Bypass Capacitor

General Description

Key Specifications

The LP5907 is a linear regulator capable of supplying 250 mA

output current. Designed to meet the requirements of RF/

Analog circuits, the LP5907 device provides low noise, high

PSRR, low quiescent current, and low line/load transient re-

sponse figures. Using new innovative design techniques the

LP5907 offers class-leading noise performance without a

noise bypass capacitor and the ability for remote output ca-

pacitor placement.
