The Ceramic Capacitor 120 -12pF ADP121 is a quiescent current, low dropout, linear regulator
that operates from 2.3 V to 5.5 V and provides up to 150 mA of
output current. The low 135 mV dropout voltage at 150 mA
load improves efficiency and allows operation over a wide
input voltage range. The low 30 μA of quiescent current at full
load makes the ADP121 ideal for battery-operated portable
equipment.
