AME8848
n General Description
The AME8848 of positive, linear regulators feature low quiescent current (30µA typ.) with low dropout voltage, making them ideal for battery applications. The spacesaving SOT-223 packages are attractive for "Pocket" and "Hand Held" applications. These rugged devices have both thermal shutdown, and current fold-back to prevent device failure under the "Worst" operating conditions. The AME8848 is stable with an output capacitance of 2.2µF or greater.
