AME8819 Datasheet, PDF (1/20 Pages) Analog Microelectronics – Low Dropout 600mA CMOS Regulator

AME
AME8819
Low Dropout
600mA CMOS Regulator
n General Description
The AME8819 is a CMOS linear regulator. It operated from
2.5V to 5.5V input voltage and delivers up to 300mA output
current. The AME8819 provide low quiescent current (70uA
typ) low dropout voltage (Vout=3.3V, 540mV @ 600mA typ),
and excellent PSRR, thus marking them ideal for Data-Com-
munications and battery applications.
The AME8819 provide over temperature and over current
protected functions. It is stable with an output capacitance of
2.2uF or larger.
