n General Description
The AME8816 family of positive, linear regulators fea-
ture low quiescent current (45µA 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.
The AME8816 is stable with an output capacitance of
4.7µF or greater.
