Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'G' indicates RoHS compliance as per manufacturer standards. Confirm the 6-UFDFN package dimensions match your PCB layout requirements. Ensure the fixed 2.05 V output aligns with your load specifications, as adjustable variants exist within the series. Cross-reference the datasheet for thermal dissipation limits in the chosen enclosure.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 2.05 V rail is required from a 1.8 V to 6 V source. The 3 MHz frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider the 600 mA limit against peak load demands. The exposed pad design necessitates adequate thermal relief on the PCB for reliable operation under continuous load conditions.
