THREE-TERMINAL ADJUSTABLE NEGATIVE VOLTAGE REGULATORS
LM337SP Datasheet PDF :
The LM337 series are adjustable 3-terminal negative voltage regulators capable of supplying in excess -1.5 A over a -1.2 to -37 V output voltage range. They are exceptionally easy to use and require only two external resistors to set the output voltage. Further, both line and load regulation are better than standard fixed regulators.
