DESCRIPTION

The LT1083 series of positive adjustable regulators are

designed to provide 3A, 5A and 7.5A 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 output voltage to

1%. Current limit is also trimmed, minimizing the stress

on both the regulator and power source circuitry under

overload conditions.
