The LP5900 is a linear regulator capable of supplying
150 mA output current. Designed to meet the
• Virturally Zero I
Q
(Disabled), <1 µA
requirements of RF/Analog circuits, the LP5900
• Very Low I
Q
(Enabled), 25 μA
device provides low noise, high PSRR, low quiescent
• Startup Time, 150 μs
current, and low line transient response figures. Using
new innovative design techniques the LP5900 offers
• Low Dropout, 80 mV Typ.
class-leading device noise performance without a
noise bypass capacitor.
