Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'XMH' against the official datasheet to confirm the package type and tape/reel specifications. Ensure the 'Q0' designation aligns with your quality requirements, as it differs from the 'Q1' automotive grade. Confirm RoHS compliance status through the manufacturer's documentation before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when dual isolated outputs are required within a compact footprint. The 2.2MHz frequency allows for smaller external inductors compared to lower-frequency alternatives. Ensure the thermal design supports the 16-WQFN package constraints. Verify that the input voltage never exceeds 5.5V to prevent device damage.
