AV1084T

@vic 5A Adjustable Low Dropout Linear Regulator (LDO) FEATURES AV1084 TO-252, 263, 220 GENERAL DESCRIPTION The AV1084 is a positive and low dropout three-terminal voltage regulator with 5A output current capability. This device is designed for use in low voltage applications that offers lower dropout voltage and faster transient response. 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 AV1084 Series regulators are available in the popular industry standard TO-220, TO-263 and TO-252 packages. Very easy to use, it requires only two external resistors to set the output voltage Low dropout voltage: 1.2V typical at up to 5A Low ground current Fast transient response Current & thermal limiting Line regulation: 0.5% typical Load regulation: 0.5% typical TO-220, TO-263 and TO-252 packages APPLICATIONS High current microprocessor supplies Low voltage logic supply Powering VGA & sound card Portable instrumentation Constant current regulator Post regulator for switching power supply TYPICAL APPLICATION Vin IN AV 1084 OUT ADJ Vref Vout R1 + Cin 10uF + Cout 10uF Iadj R2 Vo = Vref (1+R2/R1) + Iadj x R2 1. Cin needed if device is far from from filter capacitors. 2. Cout required for stability. - Basic Adjustable Regulator Circuit - 1 MAY-31-2001 @vic 5A Adjustable Low Dropout Linear Regulator (LDO) AV1084 TO-252, 263, 220 ABSOLUTE MAXIMUM RATINGS Maximum Supply Voltage Power Dissipation Thermal Resistance Junction to Case, θJC Thermal Resistance Junction to Ambient, θJA TO-220 TO-263 TO-252 7V Internally Limited 2.5 °C/W Operating Junction Temperature Range Storage Temperature Range Lead Temperature (Soldering, 10 Seconds) 0 to 125 °C -40 to 150 °C 260 °C 50 °C/W 60 °C/W 70 °C/W ELECTRICAL CHARACTERISTICS (Unless otherwise specified, TA = 25 °C.)
