AME8890
n General Description
The AME8890 is a fixed 1.2V of positive, linear regula-
tor feature low quiescent current (60µA typ.) with low drop-
out voltage, making them ideal for battery applications.
The space-saving SOT-25/TSOT-25 packages are attrac-
tive for "Pocket" and "Hand Held" applications.
This rugged device has both Thermal Shutdown, and
Current Fold-back to prevent device failure under the
"Worst" 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.
