| SENSITRON SEMICONDUCTOR TECHNICAL DATA DATA SHEET 4095, REV. - SHD526154 POSITIVE FIXED 3.3 VOLT 3.0 AMP VOLTAGE REGULATOR Features: * * * * * * Isolated Hermetic Package (TO-257) Three-Terminal Fixed Operates Down to 1V Dropout Guaranteed Dropout Voltage at Multiple Current Levels On-Chip Thermal Limiting Electrically Equivalent to LT1085-3.3 Applications: * * * High Efficiency Linear Regulators Post Regulator for Switching Supplies Constant Current Regulators Description: This positive +3.3V 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. Current limit is trimmed to ensure specified output current and controlled shortcircuit current. On-chip thermal limiting provides protection against any combination of overload that would create excessive junction temperatures. MAXIMUM RATINGS Parameter Input Voltage Max Storage Temperature Range Lead Temperature Power Dissipation (PD) Maximum Thermal Resistance Junction to Case ( JC) Junction Temperature (TJ) Ambient Operating Temperature Range (TA) Output Current (IOUT) Input Voltage Conditions Transient - All ratings are at TA = 25C unless otherwise specified.
