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 is 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 current limit, thermal
overload protection and safe area protection. All overload protection circuitry
remains fully functional even if the adjustment terminal is disconnected.
