n General Description
nn
The AME8816 family of positive, linear regulators feature 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 .
