The LM337 is an adjustable 3−terminal negative voltage regulatorcapable of supplying in excess of 1.5 A over an output voltage range of−1.2 V to −37 V. This voltage regulator is exceptionally easy to useand requires only two external resistors to set the output voltage.Further, it employs internal current limiting, thermal shutdown andsafe area compensation, making it essentially blow−out proof.The LM337 serves a wide variety of applications including local, oncard regulation. This device can also be used to make a programmableoutput regulator, or by connecting a fixed resistor between theadjustment and output, the LM337 can be used as a precision currentregulator.
