AME8803FEEY

Analog Microelectronics, Inc. AME8803/8814 300mA CMOS LDO n General Description The AME8803 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-23-6 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. In applications requiring a low noise, regulated supply, place a 1000pF capacitor between Bypass and ground. The AME8803 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 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 Noise Reduction Bypass Capacitor Power Good Detector Power-Saving Shutdown Mode Space-Saving SOT-26 (SOT-23-6) Factory Pre-set Output Voltages Low Temperature Coefficient n Applications l l l n Functional Block Diagram IN Overcurrent Shutdown l l l OUT l Instrumentation Portable Electronics Wireless Devices Cordless Phones PC Peripherals Battery Powered Widgets Electronic Scales n Typical Application IN EN IN BYP GND PG OUT Thermal Shutdown EN BYP PG V ref AME8803 OUT R1 x110% AMP C1 5V 1 µF C2 1nF C3 2.2 µF V ref x90% R2 V ref =1.215V GND 1 Analog Microelectronics, Inc.
