Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'UN' against official Renesas documentation, as standard datasheets typically list 'IRUAZ' or 'IRUFZ'. Confirm package dimensions and pinout compatibility before integration. Ensure ordering specifications match the exact thermal and electrical requirements defined in the manufacturer's latest release notes.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component for designs requiring a small footprint and high efficiency at moderate currents. The 4.3 MHz frequency allows for smaller passive components compared to lower-frequency alternatives. Verify that the required output voltage falls within the supported 0.8 V to 6 V range and that the input supply remains stable between 2.7 V and 6 V.
