Overview

The LM133/LM333 are adjustable 3-terminal negative voltage regulators capable of supplying in excess of -3.0A over an output voltage range of -1.2V to -32V. These regulators are exceptionally easy to apply, requiring only 2 external resistors to set the output voltage and 1 output capacitor for frequency compensation.
