Procurement Notes

Verify the specific suffix 'C' against the manufacturer datasheet to confirm output voltage or feature variations, as ordering suffixes may indicate distinct electrical characteristics within the R1225N series. Ensure the component matches the required SOT-23-wide-6 footprint and that the supply chain documentation confirms RoHS compliance status prior to integration.

Selection Notes

Select this component when a fixed-output buck controller is required with an input voltage capability of 18.5V. The choice depends on the necessity for combined PWM/VFM operation to optimize efficiency across varying load conditions. Verify that the SOT-23-wide-6 package fits the design constraints and that the fixed output specification aligns with the target system voltage requirements.
