AME8850

AME, Inc. AME8850 n General Description The AME8850 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/TSOT-25, SOP-8 & DFN8(3mmx3mmx0.75mm) 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 AME8850 is stable with an output capacitance of 2.2µF or greater. 600mA CMOS LDO n Functional Block Diagram IN OUT Overcurrent Shutdown Thermal Shutdown EN AMP ADJ n Features l Very Low Dropout Voltage l Guaranteed 600mA Output l Typical 30µA Quiescent Current l Output Voltage Accurate to within 2.5% l Over-Temperature Shutdown l Current Limiting l Short Circuit Current Fold-back l Power-Saving Shutdown Mode l Space-Saving SOT-25/TSOT-25, SOP-8 & DFN-8 (3mmx3mmx0.75mm) Packages l User Adjustable Output Voltages l Low Temperature Coefficient l All AME's Lead Free Products Meet RoHS Standards VREF =1.2V GND n Typical Application IN C1 1µ F R2 EN IN OUT OUT C2 R1 100p C3 2.2µF AME8850 GND ADJ n Applications l Instrumentation l Portable Electronics l Wireless Devices l Cordless Phones l PC Peripherals l Battery Powered Widgets VOUT = 1.2 ( R1/R2 +1 ) C2 is unnecessary if R1 or R2 < 20 K Ohms R R and R use resistance value within 1% accuracy for 1 2 a n d correct VOUT Rev.B.01 1 Free Datasheet http:...
