AME8840OEEV

Analog Microelectronics, Inc. AME8801/8812/8840 300mA CMOS LDO n General Description The AME8801/8840 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. In applications requiring a low noise, regulated supply, place a 1000 pF capacitor between Bypass and Ground. The AME8801 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 Noise Reduction Bypass Capacitor Power-Saving Shutdown Mode Space-Saving SOT-25 (SOT-23-5) Package 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 n Typical Application INPUT OUTPUT IN BYP GND OUT Thermal Shutdown EN BYP AMP AME8801 R1 C1 5V C2 EN C3 2.2 µF 1 µF 1nF V ref = 1 . 2 1 5 V R2 GND 1 Analog Microelectronics, Inc.
