AME8819_12 Datasheet, PDF (1/22 Pages) Analog Microelectronics – Low Dropout 600mA CMOS Regulator

AME
AME8819
Low Dropout
600mA CMOS Regulator
„ General Description
The AME8819 is a CMOS linear regulator. It operated from
2.8V to 5.5V input voltage and delivers up to 600mA output
current. The AME8819 provide low quiescent current (70μA
typ) low dropout voltage (Vout=3.3V, 540mV @ 600mA typ),
and excellent PSRR, thus marking them ideal for Data-Com-
munications and battery applications.
