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.
