11.22. LM1084

11.22.1. General description
The LM1084 is a series of low dropout voltage positive regulators with a maximum dropout of 1.5V at 5A of
load current. The LM1084 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: 3.3V, 5.0V and 12.0V. The fixed versions
intergrate the adjust resistors. The LM1084 circuit includes a zener trimmed bandgap reference, current
limiting and thermal shutdown. The LM1084 series is available in TO-220 and TO-263 pack-ages.
