Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the exact suffix 'R-G' corresponds to the specific tape-and-reel packaging configuration required for your assembly line. Confirm that the fixed 4.0V output aligns with your circuit design needs, as this variant does not offer adjustable output options. Ensure compatibility with your PCB footprint regarding the SOT-25-6 package dimensions before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this model when a fixed 4.0V output is required from low-voltage sources like single-cell lithium batteries. Consider the operating frequency range based on available inductor sizes; higher frequencies allow smaller magnetics but may increase switching losses. Verify that the input voltage range covers your minimum source voltage to ensure proper startup and regulation under all conditions.
