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