Description
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. Also, LM337
regulators are supplied in standard
transistor packages which are easily mounted and handled. In addition to higher performance than fixed
regulators, the LM337 series offer full overload protection available only in integrated circuits. Included on the chip are
