Application Scenarios & Design Considerations

Adjustable Precision Shunt Regulator

Alternative Part Number

  • LMV431AIM5 --: Adjustable shunt regulator in SOT-23-5 with 1% tolerance, functionally equivalent to TL432 and pin-compatible in most designs.
  • AZ431AN-BTRE1 --: Precision adjustable shunt regulator in SOT-23, 1% reference tolerance, widely used as a TL432 drop-in alternative.
  • KA431AZBU --: Industry-standard adjustable shunt regulator in TO-92/SOT-23 family, 1% tolerance, well-established TL432 replacement.
  • AZ432ANTR-E1 --: 1.24V adjustable precision shunt regulator in SOT-23, similar accuracy and current capability, suitable replacement for TL432A applications.
  • TS432AILT --: 1.24V adjustable shunt voltage reference in SOT-23-3 with 0.5% grade, comparable electrical behavior and pinout for TL432A designs.
