AME8845

AME, Inc. AME8845 3A CMOS LDO n General Description The AME8845 family of linear regulators feature low quiescent current (100µA typ.) with low dropout voltage, making them ideal for battery applications. It is available in TO-252, SOT-223, TO-263 and TO-220 packages. The www.DataSheet4U.com space-efficient TO-252, SOT-223 package is attractive for "Pocket" and "Hand Held" applications. Output voltages are set at the factory and trimmed to 1.5% accuracy. These rugged devices have both Thermal Shutdown, and Current Fold-back to prevent device failure under the "Worst" of operating conditions. The AME8845 is stable with an output capacitance of 2.2µF or greater. n Functional Block Diagram IN Overcurrent Shutdown OUT Thermal Shutdown EN R1 AMP + R2 Vref n Features l Very Low Dropout Voltage l Guaranteed 3A Output l Accurate to within 1.5% l 100µA Quiescent Current Typically l Over-Temperature Shutdown l Current Limiting l Short Circuit Current Fold-back l Space-Saving TO-252, SOT-223, TO-263 and TO-220 Package l Low Temperature Coefficient 0.1µ F VIN IN EN GND n Typical Application SENSE AME8845 OUT GND 2.2µF n Applications l Instrumentation l Portable Electronics l Wireless Devices l PC Peripherals l Battery Powered Widgets 1 AME, Inc.
