AME
600mA CMOS LDO
AME8805 / 8813
n General Description
n Functional Block Diagram
TheAME8805/8813 family of positive, linear regulators
feature low quiescent current (30mA typ.) with low drop-
out voltage, making them ideal for battery applications.
The space-saving SOT-89, SOT-223 and SOT-23 pack-
ages are attractive for "Pocket" and "Hand Held" applica-
tions.
