LT1083/LT1084/LT1085 Fixed

3A, 5A, 7.5A Low Dropout

Positive Fixed Regulators

FeaTures

DescripTion

The

1083

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.

The LT1083 series devices are pin compatible with older

three-terminal regulators. A 10µF output capacitor is

required on these new devices; however, this is usually

included in most regulator designs.

Unlike PNP regulators, where up to 10% of the output cur-

rent is wasted as quiescent current, the LT1083 quiescent

current flows into the load, increasing efficiency.
