General Description
The AME8807 family of positive, linear regulators fea-
ture low ground current (30µA Typ.) with low dropout volt-
age, making them ideal for battery applications. The
space-saving SOP-8 & DFN-8 (3mmx3mmx0.6mm) pack-
ages are 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 AME8807 is stable with an output capacitance of
2.2µF or greater.
