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, 2.3V, 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.
