AME8824

www.DataSheet4U.com AME, Inc. 300mA CMOS LDO AME8824 n General Description 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. These rugged devices have both Thermal Shutdown, and Current Fold-back to prevent device failure under the "Worst" of operating conditions. The SOT-26 version also features a "Power Good" detector, which pulls low when the output is out of regulation. The AME8824 is stable with an output capacitance of 2.2µF or greater. n Functional Block Diagram IN OUT Overcurrent Shutdown Thermal Shutdown EN Vref x110% PG ADJ AMP n Features l Very Low Dropout Voltage l Guaranteed 300mA Output l Typical accuracy within 2% l 30µA Quiescent Current l Over-Temperature Shutdown l Current Limiting l Short Circuit Current Fold-back l Power Good Detector (6 pin version only) l Power-Saving Shutdown Mode l Space-Saving SOT-26 l Adjustable Output Voltages l Low Temperature Coefficient IN Vref x90% Vref =1.2V GND n Typical Application EN IN PG OUT OUT C2 R1 100p C3 2.2µ F R2 AME8824 GND ADJ C1 5V 1µ F n Applications l Instrumentation l Portable Electronics l Wireless Devices l Cordless Phones l PC Peripherals l Battery Powered Widgets l Electronic Scales V OUT = 1.2 (R1 +R2)/R2 C2 is unnecessary when R1 or R2 < 20K PG pin is only available in the SOT-26 package op...
