Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific suffix matches the required output voltage and package type. Check for end-of-life status as the XC9260/XC9261 series may be discontinued for new designs. Ensure compliance with RoHS standards and verify thermal performance requirements for the intended operating environment before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this model when a fixed 3V output is required with up to 1.5A load capacity. Consider the 6-UFDFN package for space-constrained PCB layouts. Evaluate the need for synchronous rectification to maximize efficiency at higher loads. Verify that the input voltage range of 2.7V to 5.5V aligns with the system's power source. Assess thermal dissipation capabilities given the exposed pad design for heat sinking.
