Product Summary

The LM337T is adjustable 3-terminal negative voltage regulator capable of supplying in excess of −1.5A over an output voltage range of −1.2V to −37V. The LM337T is exceptionally easy to apply, requiring only 2 external resistors to set the output voltage and 1 output capacitor for frequency compensation. The LM337T 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 LM337T serves a wide variety of applications including local on-card regulation, programmable-output voltage regulation or precision current regulation. The LM337T is ideal complements to the LM117/LM317 adjustable positive regulators.
