LP5900

Ultra Low Noise, 150 mA Linear Regulator for RF/Analog

Circuits Requires No Bypass Capacitor

General Description

The LP5900 is a linear regulator capable of supplying 150 mA

output current. Designed to meet the requirements of RF/

Analog circuits, the LP5900 device provides low noise, high

PSRR, low quiescent current, and low line transient response

figures. Using new innovative design techniques the LP5900

offers class-leading device noise performance without a noise

bypass capacitor.

The device is designed to work with 0.47 μF input and output

ceramic capacitors. (No Bypass Capacitor is required)

The device is available in micro SMD package and LLP pack-

age. For all other package options contact your local NSC

sales office.

This device is available with 1.5V,1.575V, 1.8V, 1.9V, 2.0V,

2.1V, 2.2V, 2.5V, 2.6V, 2.7V, 2.75V 2.8V, 2.85V 3.0V, and

3.3V outputs. Please contact your local sales office for any

other voltage options.
