Descriptions of LM137K
The LM137 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, LM137 regulators are supplied in
standard transistor packages which are easily mounted and handled. In addition to higher
performance than fixed regulators, the LM137 series offer full overload protection available only
in integrated circuits. Included on the chip are current limit, thermal overload protection and safe
area protection. All overload protection circuitry remains fully functional even if the adjustment
terminal is disconnected.
