Description

This is 1.5A Low Dropout Positive Regulators. 1.5A Low Dropout Positive Regulators August 1999 LM1086 1.5A Low Dropout Positive Regulators General 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 three fixed voltages: 2.85V, 3.3V 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 and TO-263 packages. D-Pak is available upon special request; contact the National Semiconductor sales representative in your area.
