AME
AME8800 / 8811
300mA CMOS LDO
n General Description
The AME8800/8811 family of positive, linear regulators
feature low quiescent current (30µA 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.
These rugged devices have both Thermal Shutdown,
and Current Fold-back to prevent device failure under the
"Worst" of operating conditions.
The AME8800/8811 is stable with an output capacitance
of 2.2µF or greater.
