AME8808MEGT

Analog Microelectronics, Inc. AME8808 750mA CMOS LDO n General Description The AME8808 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 and DPAK-2 packages 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. n Features l l l l l l l l l l The AME8808 is stable with an output capacitance of 2.2µF or greater. 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 and DPAK-2 Package Factory Pre-set Output Voltages Low Temperature Coefficient n Applications l l n Functional Block Diagram IN OUT l l l l l Instrumentation Portable Electronics Wireless Devices Cordless Phones PC Peripherals Battery Powered Widgets Electronic Scales Overcurrent Shutdown Thermal Shutdown R1 n Typical Application IN IN OUT AME8808 GND OUT AMP C1 5V V ref=1.215V R2 GND C2 2.2µF 1 µF 1 Analog Microelectronics, Inc.
