n General Description
The AME8841 linear regulator features low quiescent cur-
rent (30µA typ.) with low dropout voltage, making it ideal
for battery applications. The space-saving SO-8 pack-
age is attractive for "Pocket” and "Hand Held" applica-
tions.
These rugged devices have both Thermal Shutdown,
and Current Fold-back to prevent device failure under
the "Worst" of operating conditions.
The AME8841 is stable with an output capacitance of
2.2µF or greater.
