3 Description
The LM1086 is a regulator with a maximum dropout
of 1.5 V at 1.5 A of load current. The device has the
same pin-out as TI's industry standard LM317.
Two resistors are required to set the output voltage of
the adjustable output voltage version of the LM1086.
Fixed output voltage versions integrate the adjust
resistors.
The LM1086 circuit includes a zener trimmed
bandgap reference, current limiting, and thermal
shutdown.
Refer to LM1084 for the 5-A version, and the LM1085
for the 3-A version.
