AME8818  
¢ General Description  
¢ Functional Block Diagram  
TheAME8818 is a CMOS linear regulator. It operated from  
2.5V to 5.5V input voltage and delivers up to 300mA output  
current. TheAME8818 provide low quiescent current (70µA  
typ) low dropout voltage (230mV @ 300mA typ), and excel-  
lent PSRR, thus marking them ideal for Data-Communica-  
tions and battery applications.
