300mA CMOS LDO
AME8824
n General Description
n Functional Block Diagram
TheAME8824 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 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.

The SOT-26 version also features a "PowerGood" de-
tector, which pulls low when the output is out of regula-
tion.
