AME, Inc. AME8843 750mA CMOS LDO n General Description The AME8843 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-223 package is 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 AME8843 is stable with an output capacitance of 2.2µF or greater. n Functional Block Diagram IN OUT Overcurrent Shutdown Thermal Shutdown R1 AMP Vref=1.215V R2 GND n Features l l l l l l l l l l Very Low Dropout Voltage Guaranteed 750mA Output Accurate to within 1.5% 30µA Quiescent Current Over-Temperature Shutdown Current Limiting Short Circuit Current Fold-back Space-Saving SOT-223 Package Factory Pre-set Output Voltages Low Temperature Coefficient n Typical Application IN IN OUT AME8843 OUT GND C1 5V 1µ F C2 2.2µ F n Applications l l l l l l l Instrumentation Portable Electronics Wireless Devices Cordless Phones PC Peripherals Battery Powered Widgets Electronic Scales 1 AME, Inc.
