AME8848AEGT330Z

AME AME8848 n General Description The AME8848 of positive, linear regulators feature low quiescent current (30µA typ.) with low dropout voltage, making them ideal for battery applications. The spacesaving SOT-223 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" operating conditions. The AME8848 is stable with an output capacitance of 2.2µF or greater. 1A CMOS LDO n Functional Block Diagram IN OUT Overcurrent Shutdown Thermal Shutdown R1 AMP n Features l Very Low Dropout Voltage l Guaranteed 1A Output l Accurate to within + 1.5% l 30µA Quiescent Current l Over-Temperature Shutdown l Current Limiting l Short Circuit Current Fold-back l Space-Saving SOT-223 Packages l Factory Pre-set Output Voltages l Low Temperature Coefficient l All AME's Lead Free Products Meet RoHS Standards IN Vref=1.215V R2 GND n Typical Application AME8848 OUT GND OUT IN C1 5V 1µF C2 2.2µ F n Applications l Instrumentation l Portable Electronics l Wireless Devices l Cordless Phones l PC Peripherals l Battery Powered Widgets Rev.A.04 1 AME AME8848 n Pin Configuration SOT-223 Top View AME8848AEGT 1.
