n General Description  
n Functional Block Diagram  
(Fixed Version)  
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.
