Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix (V+T) indicates tape-and-reel packaging when ordering. Confirm AEC-Q100 compliance requirements match your target application standards. Ensure the TQFN-EP-24 footprint matches your PCB layout constraints. Cross-reference the datasheet for thermal pad soldering recommendations to ensure reliable operation.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing systems requiring three distinct voltage rails from a single low-voltage source. It is suitable for applications where board space is limited due to its integrated topology. Consider the 2.2MHz frequency for smaller passive components compared to lower-frequency alternatives. Verify that the total output current requirements do not exceed the individual channel limits.
