AME8816
nGeneral Description
nFunctional Block Diagram
(Fixed Versions)
TheAME8816 family of positive, linear regulators fea-
ture low quiescent current (45mA typ.) with low dropout
voltage, making them ideal for battery applications.

Shutdown
Output voltages are set at the factory and trimmed to
1.5% accuracy.
R1
These rugged devices have both Thermal Shutdown,
and Current Fold-back to prevent device failure under the
"Worst" operating conditions.

In applications requiring a low noise, regulated supply,
place a 1000pF capacitor between Bypass andGround.
R2
1.242V
The AME8816 is stable with an output capacitance of
4.7mF or greater.
