Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify that the specific part number matches the required fixed output voltage of 3.09V, as this value is not adjustable. Confirm package compatibility with the DFN-8 footprint during PCB layout. Ensure input voltage sources remain within the specified 3.25V to 5.5V range to maintain proper regulation. Check for RoHS compliance documentation if environmental standards are mandatory for your assembly process.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing circuits for single-cell lithium-ion systems where space constraints limit external passive components. The fixed 3.09V output makes it suitable for powering logic or analog sections directly without additional regulation stages. Consider the 2MHz switching frequency for enabling smaller inductors compared to lower-frequency alternatives. Evaluate the 650mA current limit against peak load requirements to ensure adequate headroom.
