Procurement Notes

Verify the exact suffix 'WECC' against official manufacturer documentation, as standard listings typically utilize 'WEB'. Confirm availability status, as many variants in this series are marked as obsolete or discontinued. Ensure compliance with RoHS specifications if required for the target application environment.

Selection Notes

Select this component when designing for low-noise requirements in cellular applications. The fixed 3V output simplifies design for specific logic levels. Consider the 2MHz frequency for smaller inductor selection compared to lower-frequency alternatives. Verify thermal dissipation capabilities within the small WLP footprint for the intended load conditions.
