300mA CMOS Regulator
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 (70µA
typ) low dropout voltage (230mV @ 300mA typ), and excel-
lent PSRR, thus marking them ideal for Data-Communica-
tions and battery applications.
The AME8818 provide over temperature and over current
protected functions. It is stable with an output capacitance of
1µF or larger.
