Power Good Output Function.
The AME8844 family of positive, linear regulators fea-
ture low quiescent current (45
μ
A 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.
An additional feature is a
“
Power Good
”
detector, which
pulls low when the output is out of regulation.
The AME8844 is stable with an output capacitance of
4.7
μ
F or greater.
