LM337T IC - Variable Negative Voltage Regulator IC

LM337T (LM337) Variable Negative Voltage Regulator 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. The IC commonly used in Adjustable Lab Voltage generators in combination with the LM317 IC. It can also be used as Current Regulators and negative voltage protection circuits, refer to the datasheet linked below for application circuits.
