AME8805 / 8810
n n n n n
The AME8805/8810 family of positive, linear regula-
tors feature low quiescent current (30 A typ.) with low
dropout voltage, making them ideal for battery applica-
tions. The space-saving SOT-89 and SOT-223 pack-
ages are attractive for "Pocket" and "Hand Held" appli-
cations.
These rugged devices have both Thermal Shutdown,
and Current Fold-back to prevent device failure under
the "Worst" of operating conditions.
The AME8805/8810 is stable with an output capacitance
of 2.2 F or greater.

... CMOS LDO External Capacitors The AME8805/8810 is stable with an output capacitor to ground of 2 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. Un- fortunately, large value ceramic capacitors are compara- tively expensive ...
