9.9.1.
Description
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 five fixed voltages: 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 band-gap
reference, current limiting and thermal shutdown.
