AME8819

General Description

The AME8819 is a CMOS linear regulator. It operated from

2.5V to 5.5V input voltage and delivers up to 600mA 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.
