ADP151 Datasheet - Analog Devices

ADP151 CMOS Linear Regulator

The ADP151 is an ultralow noise, low dropout (LDO) linear regulator that operates from 2.2 V to 5.5 V and provides up to 200 mA of output current. The low 135 mV dropout voltage at 200 mA load improves efficiency and allows operation over a wide input voltage range. Using an innovative circuit topol.
