The LM137 is a high voltage adjustable 3-terminal

voltage regulator with guaranteed 1.5A output current

and equipped with internal limiting + thermal shutdown

features for overload immunity. Output voltage is set

by two external resistors. Additional to standard

regulator function, the device can be used as a simple

adjustable switching regulator; a programmable output

regulator; or by connecting a fixed resistor between

adjustment pin and output, can be used as a precision

current regulator. A shutdown mechanism can be

introduced by clamping the adjust terminal to ground

which programs output to -1.2V where most loads

draw little current.
