3A, 5A, 7.5A Low Dropout

Positive Fixed Regulators

FEATURES

DESCRIPTIO

The LT^®1083 series of positive adjustable regulators are

designedtoprovide3A, 5Aand7.5Awithhigherefficiency

than currently available devices. All internal circuitry is

■

Three-Terminal 3.3V, 3.6V, 5V and 12V

■

Output Current of 3A, 5A or 7.5A

■

Operates Down to 1V Dropout

■

Guaranteed Dropout Voltage at Multiple Current Levels designedtooperatedownto1Vinputtooutputdifferential

■

Line Regulation: 0.015%

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.

Load Regulation: 0.1%

100% Thermal Limit Functional Test

Adjustable Versions Available

APPLICATIO S

■

High Efficiency Linear Regulators

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.

■

Post Regulators for Switching Supplies

■

Constant Current Regulators

Battery Chargers

■

DEVICE

OUTPUT CURRENT*

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

current is wasted as quiescent current, the LT1083 quies-

cent current flows into the load, increasing efficiency.
