LM1086

1.5A Low Dropout Positive Regulators

General Description

Features

n Available in 1.8V, 2.5V, 2.85V, 3.3V, 3.45V, 5V and

Adjustable Versions

The LM1086 is a series of low dropout positive voltage

regulators with a maximum dropout of 1.5V at 1.5A of load

current. It has the same pin-out as National Semiconductor’s

industry standard LM317.

n Current Limiting and Thermal Protection

n Output Current

1.5A

The LM1086 is available in an adjustable version, which can

set the output voltage with only two external resistors. It is

also available in six fixed voltages: 1.8V, 2.5V, 2.85V, 3.3V,

3.45V and 5.0V. The fixed versions integrate the adjust

resistors.

Applications

n SCSI-2 Active Terminator

n High Efficiency Linear Regulators

n Battery Charger

The LM1086 circuit includes a zener trimmed bandgap ref-

erence, current limiting and thermal shutdown.

The LM1086 series is available in TO-220, TO-263, and LLP

packages. Refer to the LM1084 for the 5A version, and the

LM1085 for the 3A version.
