LT1086 Series

1.5A Low Dropout Positive

Regulators Adjustable and

Fixed 2.85V, 3.3V, 3.6V, 5V, 12V

FEATURES

DESCRIPTION

The LT^®1086 is designed to provide 1.5A 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 speci-

■

3-Terminal Adjustable or Fixed

2.85V, 3.3V, 3.6V, 5V, 12V

■

Output Current of 1.5A, (0.5A for LT1086H)

■

Operates Down to 1V Dropout

■

Guaranteed Dropout Voltage at Multiple Current Levels fied as a function of load current. Dropout is guaranteed at

■

Line Regulation: 0.015%

a maximum of 1.5V at maximum output current, decreas-

ing at lower load currents. On-chip trimming adjusts the

reference/ouput 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

APPLICATIONS

TheLT1086ispincompatiblewitholder3-terminaladjust-

able regulators. A 10µF output capacitor is required on

these new devices; however, this is usually included in

most regulator designs.

■

SCSI-2 Active Terminator

■

High Efficiency Linear Regulators

■

Post Regulators for Switching Supplies

Constant Current Regulators

Battery Chargers

■

A 2.85V output version is offered for SCSI-2 active termi-

nation. For surface mount applications see the LT1117-

2.85datasheet. Forhighcurrentorlowerdropoutrequire-

ments see the LT1123-2.85 data sheet.

■

Microprocessor Supply

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

current is wasted as quiescent current, the LT1086 quies-

cent current flows into the load, increasing efficiency.
