The AME8890 is a fixed 1.2V of positive, linear regula-
tor feature low quiescent current (30µA typ.) with low
dropout voltage, making them ideal for battery applica-
tions. The space-saving SOT-23-5 package is attractive
for "Pocket" and "Hand Held" applications.
This rugged device has 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 AME8890 is stable with an output capacitor of
2.2µF or greater.
