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.
