3A CMOS LDO
n General Description
The AME8845 family of linear
regulators feature low quiescent current (100µA 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. The www.DataSheet4U.com space-efficient TO-252, SOT-223 package is 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 AME8845 is stable with an output capacitance of 2.2µF or greater.
