Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix ACWE+ against official datasheets to confirm the fixed 3.3V output variant and commercial temperature grade. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as regulatory markings may vary by production batch. Ensure the SOIC-16 footprint matches your PCB design constraints before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a stable 3.3V rail is required without the need for adjustable output programming. It is suitable for applications where the input voltage exceeds 3.3V but remains below 16V. Consider the 500mA current limit and 212.5 kHz switching frequency when designing the external inductor and capacitor network to ensure adequate performance and stability.
