Product Summary

The LM1086 is a series of low dropout positive voltage regulators with a maximum dropout of 1.5V at 1.5A of load current. It has the same pin-out as National Semiconductor’s industry 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 six fixed voltages: 1.8V, 2.5V, 2.85V, 3.3V,3.45V and 5.0V. The fixed versions integrate the adjust resistors.The LM1086 circuit includes a zener trimmed bandgap reference,current limiting and thermal shutdown.The LM1086 series is available in TO-220, TO-263, and LLP packages. Refer to the LM1084 for the 5A version, and the LM1085 for the 3A version.
