GS1086 New Product Vishay Semiconductors formerly General Semiconductor 1.5A Low Dropout Positive Adjustable Regulator SOT-223 TO-252 (DPak) TO-220AB TO-263AB (D2Pak) 1 2 3 1 1 2 3 2 3 GS1086CST GS1086CE 2 1 3 GS1086CT GS1086CM Pin Definition 1. Adjust/Gnd. 2. Vout (tab) 3. Vin Description The GS1086 is a low dropout three terminal regulator with 1.5A output current capability. The output voltage is adjustable with the use of a resistor divider. For fixed output voltage versions, the output voltage is internally set at 2.5V, 2.85V, 3.3V or 5V. Dropout is guaranteed at a maximum of 1.5V at maximum output current. Its low dropout voltage and fast transient response make it ideal for low voltage microprocessor applications. Internal current and thermal limiting provides protection against any overload condition that would create excessive junction temperatures. Features • Dropout Voltage 1.3V at 1.5A Output Current • Fast Transient Response • Line Regulation typically at 0.015% • Load Regulation typically at 0.1% • Internal thermal and current limiting • Adjustable Output Voltage or Fixed 2.5V, 2.85V, 3.3V, 5V • Standard 3-Pin Power Packages Functional Block Diagram Applications • Post Regulator for Switching Supply • Battery Chargers • Constant-Current Regulators • PC Add-On Card Mechanical Data VIN Current Amp Case: TO-220AB, TO-263AB (D2PAK), TO-252 (DPAK) and SOT-223 High temperature soldering guaranteed: 260°C/10 seconds at terminals VREF 1.25V 55µA + + GM -- Thermal Limit Current Limit VOUT Case outlines are on the back page For fixed voltage device ADJ GND Document Number 74801 12-Mar-02 www.vishay.com 1 GS1086 Vishay Semiconductors formerly General Semiconductor Maximum Ratings and Thermal Characteristics Parameter Vin Pin to ADJ/GND Pin Thermal Resistance – Junction to Case TO-220AB TO-252 TO-263AB SOT-223 Operating Junction Temperature Range Storage Temperature Range (TA = 25°C unless otherwise noted) Symbol Vin Value 7 3.0 8.0 3.0 15.0 0 to +125 – 65 to 150 Unit V RθJC °C/W TJ Tstg (2) °C °C Electrical Characteristics (1) Parameter TJ = 25°C , VIN = 5V, Io = 10mA unless otherwise noted.
