Technical Attributes

DESCRIPTIONThe LT ®1086 is designed to provide 1.5A with higher efficiency than currently available devices. All internal circuitry is designed to operate down to 1V input-to output differential and the dropout voltage is fully specified as a function of load current. Dropout is guaranteed at a maximum of 1.5V at maximum output current, decreasing at lower load currents. On-chip trimming adjusts the reference/ouput voltage to 1%. Current limit is also trimmed, minimizing the stress on both the regulator and power source circuitry under overload conditions.The LT1086 is pin compatible with older 3-terminal adjustable regulators. A 10µF output capacitor is required on these new devices; however, this is usually included in most regulator designs.A 2.85V output version is offered for SCSI-2 active termination. For surface mount applications see the LT1117-2.85 data sheet. For high current or lower dropout require ments see the LT1123-2.85 data sheet.Unlike PNP regulators, where up to 10% of the output current is wasted as quiescent current, the LT1086 quiescent current flows into the load, increasing efficiency.FEATURES■ 3-Terminal Adjustable or Fixed 2.85V, 3.3V, 3.6V, 5V, 12V■ Output Current of 1.5A, (0.5A for LT1086H)■ Operates Down to 1V Dropout■ Guaranteed Dropout Voltage at Multiple Current Levels■ Line Regulation: 0.015%■ Load Regulation: 0.1%■ 100% Thermal Limit Functional TestAPPLICATIONS■ SCSI-2 Active Terminator■ High Efficiency Linear Regulators■ Post Regulators for Switching Supplies■ Constant Current Regulators■ Battery Chargers■ Microprocessor Supply
