AME8800 / 8811
300mA CMOS LDO

General Description
The AME8800/8811 family of positive, linear regula-
tors feature low quiescent current (30µA typ.) with low
dropout voltage, making them ideal for battery applica-
tions. The space-saving SOT-23, SOT-25, SOT-89 and
TO-92 packages are attractive for "Pocket" and "Hand
Held" aplications.
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.
