AME8800 / 8811
300mA CMOS LDO
n Functional Block Diagram
n General Description
The AME8800/8811 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-23, SOT-25, SOT-89 and TO-92
packages are attractive for "Pocket" and "Hand Held" ap-
plications.
