General Description

The AME8817 family of positive, linear regulators feature 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.

The AME8817 is stable with an output capacitance of 4.7μF or greater.
