Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'W' against official Renesas documentation to confirm the fixed 3.3 V output variant. Check datasheets for RoHS compliance status and lead-free marking requirements. Confirm end-of-life notifications or production discontinuation notices prior to procurement planning. Ensure the ordering part number matches the exact tape and reel specifications required for assembly processes.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.3 V rail is required from a 2.7 V to 6 V source. The 4.3 MHz frequency allows for smaller external passive components compared to lower-frequency regulators. Consider the 500 mA current limit for loads requiring moderate power. Evaluate thermal performance within the specified -40°C to +85°C ambient range. Compare against adjustable variants if system flexibility is needed.
