LP5900
Ultra Low Noise, 100 mA Linear Regulator for RF/Analog
Circuits Requires No Bypass Capacitor
General Description
The LP5900 is a linear regulator capable of supplying 100
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)
This device is available with 1.5V, 1.8V, 2.0V, 2.2V, 2.5V,
2.8V, 3.0V, and 3.3V outputs. Please contact your local sales
office for any other voltage options.
