AME8861

AME, Inc. AME8861 600mA CMOS LDO n General Description The AME8861 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-25 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 AME8861 is stable with an output capacitance of 2.2µF or greater. n Functional Block Diagram IN OUT Overcurrent Shutdown Thermal Shutdown EN BYP AMP R1 n Features l l l l l l l l l Very Low Dropout Voltage 600mA 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 Vref=1.215V R2 GND n Typical Application INPUT IN OUT OUTPUT AME8861 BYP GND EN l Space-Saving SOT-25 Package l Factory Pre-set Output Voltages l Low Temperature Coefficient C1 5V 1µ F C2 1000pF C3 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 Free Datasheet http://www.datasheet4u.com/ AME, Inc.
