com LP5900 Ultra Low Noise, 100 mA Linear Regulator for RF/Analog Circuits Requires No Bypass Capacitor July 2005 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.
