General Description

Functional Block Diagram

(Fixed Version)

TheAME8819 is a CMOS linear regulator. It operated from

2.8V to 5.5V input voltage and delivers up to 600mA output

typ) low dropout voltage (Vout=3.3V, 540mV @ 600mAtyp),

and excellent PSRR, thus marking them ideal forData-Com-

munications and battery applications.

Thermal

Shutdown

The AME8819 provide over temperature and over current

protected functions. It is stable with an output capacitance of

2.2μF or larger.
