SHD526154 SENSITRON SEMICONDUCTOR TECHNICAL DATA DATA SHEET 4095, REV. - 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.
