Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'CMR-G' against the official Torex datasheet to confirm the SOT-753 package type and 3.6MHz switching frequency variant. Ensure compatibility with your PCB footprint design for the SC-74A outline. Cross-reference RoHS compliance status directly from the manufacturer's documentation prior to final procurement decisions.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a low-profile synchronous boost regulator is required for inputs as low as 0.65V. The 3.6MHz frequency allows for smaller external passive components compared to lower-frequency alternatives. Confirm that the 500mA load requirement fits within the thermal limits of the SOT-753 package for your specific application environment.
