General Description
The AME8863 family of positive, linear regulators fea-
ture low quiescent current (30µA typ.) with low dropout
voltage, making them ideal for battery applications. The
space-saving SOT-26 package is attractive for "Pocket"
and "Hand Held" applications.
These rugged devices have both Thermal Shutdown,
and Current Fold-back to prevent device failure under the
"Worst" of operating conditions.
An additional feature is a "Power Good" detector, which
pulls low when the output is out of regulation.
The AME8863 is stable with an output capacitance of
2.2µF or greater.
