MOTOROLA ANALOG IC DEVICE DATA
The LM337M is an adjustable three–terminal negative voltage regulator
capable of supplying in excess of 500 mA over an output voltage range of
–1.2 V to –37 V. This voltage regulator is exceptionally easy to use and
requires only two external resistors to set the output voltage. Further, it
employs internal current limiting, thermal shutdown and safe area
compensation, making it essentially blow–out proof.
The LM337M serves a wide variety of applications including local,
on–card regulation. This device can also be used to make a programmable
output regulator or by connecting a fixed resistor between the adjustment
and output. The LM337M can be used as a precision current regulator.
