产品概述
The LM137 and LM337-N are adjustable 3-terminal negative voltage regulators capable of
supplying
–1.5 A or more currents over an output voltage range of –1.25 V to –37 V. It requires only
two external resistors to set the output voltage and one output capacitor for frequency
compensation. The circuit design has been optimized for excellent regulation and low thermal
transients. Further, the LM137 and LM337-N feature internal current limiting, thermal shutdown and
safe-area compensation, making it virtually blowout-proof against overloads. The LM137 and LM337-N are ideal complements to the LM117 and LM317 adjustable positive
regulators. The LM137 has a wider operating temperature range than the LM337-N and is also offered
in military and space qualified versions.
