LM137 datasheet

Description : 

The LM137 / LM337-N are adjustable 3-terminal negative voltage regulators capable of supplying in excess of −1.5A over an output voltage range of −1.2V to −37V. These regulators are exceptionally easy to apply, requiring only 2 external resistors to set the output voltage and 1 output capacitor for frequency compensation. The circuit design has been optimized for excellent regulation and low thermal transients. Further, the LM137 series features internal
current limiting, thermal shutdown and safe-area compensation, making them virtually blowout-proof against overloads.


The IC serve a wide variety of applications including local on-card regulation,programmable-output voltage regulation or precision
current regulation. The devices are ideal complements to the LM117/LM317 adjustable positive regulators.
