AME8824
n General Description
n Functional Block Diagram
The AME8824 family of positive, linear regulators feature low quiescent current (30µA typ.) with low dropout
voltage, making them ideal for battery applications. The
space-saving SOT-26 package are 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.
EN
Vref x110%
The SOT-26 version also features a "Power Good" detector, which pulls low when the output is out of regulation.
