LM337 3-Terminal Negative Adjustable Regulator ( Reg LM337T NSC ) An adjustable, 3-terminal, negative voltage regulator capable of supplying 1.5A over a range of 1 2V to 37V. It is exceptionally easy to use and requires only two external resistors to set the output voltage. Besides having a higher performance compared with fixed regulators, the LM337 offers full overload protection with current limiting, thermal overload protection and safe area protection. All overload protection circuitry remains fully functional even if the adjustment terminal is disconnected.The adjustment terminal can be bypassed with a capacitor to ground to achieve very high ripple rejection ratios that are difficult to achieve with standard 3-terminal regulators.Output voltage is set by connecting a twin resistor divider between output and circuit ground and connecting the adjustment pin to the junction. A precision current regulator can also be made by connecting a fixed resistor only between the adjustment and output pins, and connecting the load to the adjustment pin. The device is available in TO220 package (LM337T).
