Product Summary

The lm333k is an adjustable 3-terminal negative voltage regulator capable of supplying in excess of -3.0A over an output voltage range of -1.2V to -32V. The lm333k is exceptionally easy to apply, requiring only 2 external resistors to set the output voltage and 1 output capacitor for frequency compensation. The circuit design has been optimized for excellent regulation and low thermal transients. Further, the lm333k series features internal current limiting, thermal shutdown and safe-area compensation, making them substantially immune to failure from overloads.
