Procurement Notes
Verify component authenticity through authorized Semtech distributors or certified suppliers. Confirm RoHS compliance status and check for end-of-life notifications, as availability may be limited. Ensure the specific suffix matches required tolerance and packaging specifications before procurement to avoid functional mismatches.
Selection Notes
Select this component when a low-cost, adjustable shunt reference is required in a compact SOT-23 package. Consider the 150mA output current limit and 30V maximum voltage rating against circuit requirements. Evaluate thermal stability needs and compare against alternative series like SC431L if lower noise or wider temperature ranges are necessary.
Part Context
This part belongs to the SC431 family of adjustable shunt regulators from Semtech. It serves as a cost-effective solution for voltage regulation tasks where precise adjustment is needed. The device complements fixed-reference alternatives by offering flexibility in setting output voltages via external resistors within its specified operating range.
Replacement Considerations
Direct substitutes include other SC431 variants such as SC431LISK-1TRT or SC431LCSK-2TRT, depending on required accuracy and temperature range. Verify pin compatibility and electrical specifications before substitution.
