LM337T

LM337 3-Terminal Adjustable Negative Regulators General Description The LM337 is adjustable 3-terminal negative voltageregulators 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 feature internal current limiting, thermal shutdown and safe-area compensation, making it virtually blowout-proof against overloads.
