THREE–TERMINAL  
ADJUSTABLE NEGATIVE  
VOLTAGE REGULATOR  
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.
