ADP151ACBZ-2.5-R7 IC REG LINEAR 2.5V 200MA 4WLCSP Analog Devices Inc.

 

GENERAL DESCRIPTION

The ADP151 is an ultralow noise, low dropout, linear regulator that operates from 2.2 V to 5.5 V and provides up to 200 mA of output current. The low 140 mV dropout voltage at 200 mA load improves efficiency and allows operation over a wide input voltage range.
