The LM137 are adjustable 3-terminal negative voltage regulators capable of supplying in
excess of 1.5 A over an output voltage range of −37 V to −1.2 V. 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 LM137 serve a wide variety of applications including local on-card regulation,
programmable-output voltage regulation or precision current regulation. The LM137 are ideal
complements to the LM117 adjustable positive regulators.
