Procurement Notes

Verify component authenticity through authorized channels due to potential counterfeit risks. Confirm RoHS compliance status via official documentation before integration. Ensure the specific suffix matches design requirements as variations may exist within the product family. Cross-reference datasheet revisions to validate electrical characteristics against current design specifications.

Selection Notes

Select this component for designs requiring a single-channel linear LED driver with PWM dimming support. Verify that the 120mA output current meets load requirements and that the 30V maximum input voltage aligns with the supply rail. Ensure the SOT-26 package fits the PCB layout constraints and thermal management strategy.
