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 short-
circuit current. On-chip thermal limiting provides protection against any combination of overload that would create
excessive junction temperatures.
