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.

Low Dropout, 80 mV Typ.
