LM337: Linear Voltage Regulator, Negative, Adjustable Output, 1.5 A
The LM337 is an adjustable 3-terminal negative linear voltage regulator capable of supplying in excess of 1.5 A over an output voltage range of -1.2V to -37 V. This linear 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 linear voltage regulator 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.
