LM237 and LM337
• Output Regulation Typically 0.3%
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.
