L1085

NIKO-SEM 3A Adjustable Low Dropout Linear Regulator (LDO) FEATURES L1085 TO-252,263,220 GENERAL DESCRIPTION The L1085 is a positive and low dropout three-terminal voltage regulator with 3A output current capability. This device is designed for use in low voltage applications that offers lower dropout voltage and faster transient response. www.DataSheet4U.com This device is fully protected against over current faults, over temperature operation, reversed input polarity, reversed lead insertion, transient voltage spike …etc. On-Chips trimming the reference voltage to 1% and features the low dropout of maximum 1.45 volts. The L1085 Series regulators are available in the popular industry standard TO-220 TO-263 and TO-252 packages. z Very easy to use, it requires only two external resistors to set the output voltage z Low dropout voltage: 1.3V typical at up to 3A z Low ground current z Fast transient response z Current & thermal limiting z Line regulation: 0.5% typical z Load regulation: 0.5% typical z TO-220, TO-263 and TO-252 packages APPLICATIONS z High current microprocessor supplies z Low voltage logic supply z Powering VGA & sound card z Portable instrumentation z Constant current regulator z Post regulator for switching power supply TYPICAL APPLICATION Vin IN L1085 OUT ADJ Vref Vout R1 + Cin 10uF + Cout 10uF Iadj R2 Vo = Vref (1+R2/R1) + Iadj x R2 1.
