The AME8815 family of linear regulators feature low
quiescent current (45 A typ.) with low dropout voltage,
making them ideal for battery applications. It is available
in D
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
4.7 F or greater.

... CMOS LDO External Capacitors The AME8815 is stable with an output capacitor to ground of 4 greater. Ceramic capacitors have the lowest ESR, and will offer the best AC performance. Conversely, Aluminum Electrolytic capacitors exhibit the highest ESR, resulting in the poorest AC response. Unfortunately, large value ceramic capacitors are com- paratively expensive ...
