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 three fixed voltages: 2.85V, 3.3V and 5.0V. The fixed versions integrate the adjust resistors.
