AME8802KEEV

Analog Microelectronics, Inc. AME8802 300mA CMOS LDO n General Description The AME8802 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-23-5 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. An additional feature is a "Power Good" detector, which pulls low when the output is out of regulation. The AME8802 is stable with an output capacitance of 2.2µF or greater. n Features l l l l l l l l l l l l Very Low Dropout Voltage Guaranteed 300mA Output Accurate to within 1.5% 30µA Quiescent Current Over-Temperature Shutdown Current Limiting Short Circuit Current Fold-back Power Good Output Function Power-Saving Shutdown Mode Space-Saving SOT-25 (SOT-23-5) Factory Pre-set Output Voltages Low Temperature Coefficient n Applications l l l l l l l n Functional Block Diagram IN Overcurrent Shutdown OUT Instrumentation Portable Electronics Wireless Devices Cordless Phones PC Peripherals Battery Powered Widgets Electronic Scales Thermal Shutdown n Typical Application IN AMP R1 IN PG GND OUT EN EN V ref x 1 1 0 % AME8802 C1 5V 1 µF OUT PG C2 2.2 µF V ref x 9 0 % V ref = 1 . 2 1 5 V ** R2 GND ** If output voltage specification is lower than 1.215V, Vref will be trimmed to 1.2V. 1 Analog Microelectronics, Inc.
