AME 300mA CMOS LDO AME8824 n General Description n Functional Block Diagram The AME8824 family of positive, linear regulators feature low quiescent current (30µA typ.) with low dropout voltage, making them ideal for battery applications. The space-saving SOT-26 package are attractive for "Pocket" and "Hand Held" applications. IN OUT Overcurrent Shutdown Thermal Shutdown These rugged devices have both Thermal Shutdown, and Current Fold-back to prevent device failure under the "Worst" of operating conditions. EN Vref x110% The SOT-26 version also features a "Power Good" detector, which pulls low when the output is out of regulation. AMP PG ADJ The AME8824 is stable with an output capacitance of 2.2µF or greater.
