ULTRA LOW NOISE, 150mA

LINEAR REGULATOR FOR

RF/ANALOG CIRCUITS

REQUIRES NO BYPASS

CAPACITOR



DESCRIPTION

The LR9500 is a linear regulator capable of supplying 150 mA

output current. Designed to meet the requirements of RF/Analog

circuits, the LR9500 device provides low noise, high PSRR, low

quiescent current, and low line transient response figures. Using

new innovative design techniques the LR9500 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)

This device is available with 1.5V, 1.8V, 2.0V, 2.5V, 2.7V, 2.8V,

3.0V, 3.3V, 4.0V and 4.5V outputs. Please contact your local sales

office for any other voltage options.
