LM1086

1.5A Low Dropout Positive Regulators

General Description

The LM1086 is a series of low dropout positive voltage regu-

lators with a maximum dropout of 1.5V at 1.5A of load cur-

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

dustry standard LM317.

The LM1086 is available in an adjustable version, which can

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

also available in three fixed voltages: 2.85V, 3.3V and 5.0V.

The fixed versions integrate the adjust resistors.

The LM1086 circuit includes a zener trimmed bandgap refer-

ence, current limiting and thermal shutdown.

The LM1086 series is available in TO-220 and TO-263 pack-

ages. D-Pak is available upon special request; contact the

National Semiconductor sales representative in your area.
