General Description
The AME8803/8814 family of positive, linear regulators
feature low quiescent current (30µA typ.) with low drop-
out 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. In applica-
tions requiring a low noise, regulated supply, place a
1000pF capacitor between Bypass and ground.
The AME8803/8814 is stable with an output capaci-
tance of 2.2µF or greater.
