LM1085
3A Low Dropout Positive Regulators
General Description
The LM1085 is a series of low dropout positive
voltage regulators with a maximum dropout of 1.
5V at 3A of load current.
It has the same pin-out as National Semiconductor’s 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 ...
