Preliminary
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.
