LINEAR VOLTAGE REGULATOR
THREE TERMINAL-POSITIVE-ADJUSTABLE
3.0 Amp, Low Dropout Voltage
TO-257 Hermetic Package
Features:
• 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
Applications:
• High Efficiency Linear Regulators
• Post Regulator for Switching Supplies
• Constant Current Regulators
Description: 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.

Notes:
1) See thermal regulation specification for changes in output voltage due to heating effects. Load and line regulation are measured at a constant
junction temperature by low duty cycle pulse testing.
2) Line and load regulation is guaranteed up to the maximum power dissipation in the package. Input/output differential and the output current
determine power dissipation. Guaranteed maximum output power will not be available over the full / input/output voltage range.
3) I_Full Load is defined as the maximum value of output load current as a function of the input-to-output voltage. I_Full Load is equal to 3.0 Amps.
