Application Scenarios & Design Considerations

Programmable Precision Reference

Alternative Part Number

  • LM431BCM3 --: Adjustable shunt voltage reference with 2.5V reference, similar tolerance grade and function, widely available and pin-compatible in many designs.
  • KA431AZ --: Classic adjustable shunt regulator equivalent to the TL431 family, same 2.5V reference and programmable output, good drop-in replacement.
  • AS431ANTR-G1 --: Adjustable precision shunt regulator with comparable reference voltage and tolerance, suitable alternative with different naming series.
