General Description

The UC39431 is an adjustable shunt voltage regulator with 100mA sink capability.

The architecture, comprised of an error amplifier and transconductance amplifier, gives the user separate control of the small signal error voltage frequency response along with a fixed linear transconductance.

A minimum 3MHz gain bandwidth product for both the error and transconductance amplifiers assures fast response.

Key Features

  • Multiple On-Chip Programmable Reference Voltages.
  • 0.4% Initial Accuracy.
  • 0.7% Overall Reference Tolerance.
  • 2.2V to 36.0V Operating Supply Voltage and User Programmable Reference.
  • 36.0V Operating Supply Voltage.
  • Reference Accuracy Maintained For Entire Range of Supply Voltage.
  • Superior Accuracy and Easier Compensation for Optoisolator.
