Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required tolerance and package variant. Check for obsolescence status and lead times prior to finalizing procurement plans.
Selection Notes
Select this component when a low-cost, adjustable shunt regulator with moderate accuracy is required. Ensure the design accommodates the specified temperature range and current limits. Verify compatibility with existing PCB footprints for the SOT-23-3 package.
Part Context
This part belongs to the SC431 series of two-terminal voltage references. It provides a stable reference voltage that can be adjusted using external resistors. The series is commonly used in applications requiring precise voltage control without complex circuitry.
Replacement Considerations
Compatible substitutes include TL431 variants from other manufacturers. Verify pinout compatibility and electrical specifications before substitution.
