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" 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.

Pin Description
Input voltage pin.
It should be decoupled with 1
µ
F or greater capacitor.
Ground connection pin.
Enable pin.
When pulled low, the PMOS pass transistor turns off, current consuming less
than 1µA.
Bypass capacitor connection.
To improve AC ripple rejection, connect a 1000pF capacitor to GND.
This will also provide a soft-start function.
LDO voltage regulator output pin.
It should be decoupled with a 4.7µF or greater value low ESR ceramic capacitor.
Feedback output voltage for adjustable device.
