AME8815
1.5A CMOS LDO
n General Description
The AME8815 family of linear regulators feature low quiescent current (45A typ.) with low dropout voltage, making them ideal for battery applications. It is available in D2PAK 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 4.7F or greater.
