300mA CMOS Regulator

AME8818

n General Description

n Functional Block Diagram

The AME8818 is a CMOS linear regulator. It operated from

2.5V to 5.5V input voltage and delivers up to 300mA output

current. The AME8818 provide low quiescent current (70uA

typ) low dropout voltage (230mV @ 300mA typ), and excel-

lent PSRR, thus marking them ideal for Data-Communica-

tions and battery applications.
