MARKING
DIAGRAMS LM337
The LM337 is an adjustable 3−terminal negative voltage regulator
capable 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 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 LM337 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 LM337 can be used as a precision current
regulator. D2PAK
