Application Scenarios & Design Considerations

Adjustable Precision Shunt Regulator

Alternative Part Number

  • LM431ACZ --: Adjustable shunt regulator with same 2.5V reference and pin-compatible function, widely available and a common drop-in for TL431 applications.
  • KA431AZ --: Industry-standard adjustable shunt regulator equivalent to TL431, with similar tolerance and current capability, suitable for most reference and regulation circuits.
  • AS431ANTR-G1 --: Low-cost adjustable shunt regulator offering comparable 2.5V reference and sink current, usable as a functional replacement in many designs.
  • KA431AZBU --: Industry-standard adjustable shunt regulator with 2.5V reference, pin-compatible with TL431 in TO-92 and widely used as a direct functional replacement.
