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.
