DESCRIPTION
The LT1085 is designed to provide 3A with higher efficiency than currently available devices. 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. On-
chip trimming adjusts the reference output voltage to 1%. Current limit is also trimmed, minimising the stress on both the
regulator and power source circuitry under overload conditions.
Notes:
1 Load and line regulation are measured at a constant junction temperature by low duty cycle pulse testing.
2 Power dissipation is determined by the input - output differential and the output current. Guaranteed maximum power
2
dissipation will not be available over the full input - output voltage range.
3 Dropout voltage is specified over the full output current range of the device.
