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 D
2
PAK and TO-220 packages. The space-efficient
SOT-223 and DPAK package are attractive for "Pocket"
and "Hand Held" 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.
The AME8815 is stable with an output capacitance of
4.7µF or greater.
