SENSITRON SEMICONDUCTOR TECHNICAL DATA DATA SHEET 4339, REV. - SHD526150 LINEAR VOLTAGE REGULATOR THREE TERMINAL-POSITIVE-ADJUSTABLE 3.0 Amp, Low Dropout Voltage TO-257 Hermetic Package Features: • • • • • • • • • • • Description: Three-Terminal Adjustable Operates Down to 1V Dropout Guaranteed Dropout Voltage at Multiple Current Levels On-Chip Thermal Limiting Line Regulation: 0.035% Load Regulation: 0.20% Fixed Versions Available Electrically Equivalent to LT®1085 High Efficiency Linear Regulators Post Regulator for Switching Supplies Constant Current Regulators SYMBOL Vin Vref ∆Vout/∆Vin ∆Vout/∆Vin ∆Vout/∆Iout VDO ILIM ILIM IAdj ∆IAdj IMIN IQ ∆Vin/∆Vout ∆Vout/∆T ∆Vout/∆T (% of Vout) ΤJC This positive adjustable regulator is designed to provide 3A with high efficiency using simple 3-terminal configurations. 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. Available in fixed voltages. Current limit is trimmed to ensure specified output current and controlled short-circuit current. On-chip thermal limiting provides protection against any combination of overload that would create excessive junction temperatures.
