General Description
The AME8817 family of positive, linear regulators fea-
ture low quiescent current (35µA typ.) with low dropout
voltage, making them ideal for battery applications.
Output voltages are set at the factory and trimmed to
1.5% accuracy.
These rugged devices have both thermal shutdown, and
current fold-back to prevent device failure under the "worst"
of operating conditions.
In applications requiring a low noise, regulated supply,
place a 1000pF capacitor between Bypass and Ground.
An additional feature is a "Power Good" detector, which
pulls low when the output is out of regulation.
