description/ordering information
The LM237 and LM337 are adjustable 3-terminal negative-voltage regulators capable of supplying in excess
of –1.5 A over an output voltage range of –1.2 V to –37 V. They are exceptionally easy to use, requiring only
two external resistors to set the output voltage and one output capacitor for frequency compensation. The
current design has been optimized for excellent regulation and low thermal transients. In addition, the LM237
and LM337 feature internal current limiting, thermal shutdown, and safe-area compensation, making them
virtually immune to failure by overloads.
The LM237 and LM337 serve a wide variety of applications, including local on-card regulation, programmable
output-voltage regulation, and precision current regulation.
