open-in-new Find other Linear regulators (LDO)

Description

The LM337-N-MIL is an adjustable 3-terminal negative voltage regulator 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 LM337-N-MIL features internal current limiting, thermal shutdown and safe-area compensation, making it virtually blowout-proof against overloads.

The LM337-N-MIL is an ideal complement to the LM117 and LM317 adjustable positive regulators.
