LP5904

Ultra Low Noise, 200 mA Linear Regulator for RF/Analog

Circuits - Requires No Bypass Capacitor

General Description

Key Specifications

The LP5904 is a linear regulator capable of supplying 200 mA

output current. Designed to meet the requirements of RF/

Analog circuits, the LP5904 device provides low noise, high

PSRR, low quiescent current, and low line transient response

figures. Using new innovative design techniques the LP5904

offers class-leading device noise performance without a noise

bypass capacitor and the ability for remote output capacitor

placement. An active pulldown circuit with a 280Ω resistor is

wired from the output to ground pins to quickly discharge out-

put when the device is disabled (VEN = low).
