Product Summary

The LM1085 is a low dropout positive voltage regulator with a maximum dropout of 1.5V at 3A of load current. It has the same pin-out as National Semiconductor industry standard LM317. The LM1085 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 integrate the adjust resistors. The LM1085 circuit includes a zener trimmed bandgap reference, current limiting and thermal shutdown. The LM1085 series is available in TO-220 and TO-263 packages. Refer to the LM1084 for the 5A version, and the LM1086 for the 1.5V version.
