General Description
The AME8815 family of linear regulators feature low
quiescent current (45µA typ.) with low dropout voltage,
making them ideal for battery applications. It is available
in TO-252, SOT-223, TO-263 and TO-220 packages.
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.
The AME8815 is stable with an output capacitance of
4.7µF or greater.
