n General Description
n Functional Block Diagram
OUT
The AME8863 family of positive, linear regulators fea-
ture low quiescent current (30mA 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.

Shutdown
These rugged devices have both Thermal Shutdown,
and Current Fold-back to prevent device failure under the
"Worst" of operating conditions.
