Voltage Reference Procurement Notes

Verify the specific suffix #WTRMPBF indicates automotive grade qualification and mini tape reel packaging. Confirm the B-grade designation matches the required 20ppm/°C drift specification. Ensure the 6-lead SOT-23 package aligns with board layout constraints. Check for RoHS compliance status before finalizing procurement orders.

Voltage Reference Selection Notes

Select this component when a 3V output is required with moderate precision and wide input voltage capability. The B-grade offers a balance between cost and performance for industrial environments. Consider the A-grade if tighter drift specifications are necessary. Verify that the 10mA drive current meets the load requirements of the target circuit design.

Voltage Reference FAQ

Can the LT6654BHS6-3 be used as a negative voltage reference?

Yes, by connecting the output to a negative rail and biasing the internal circuitry with a positive voltage at the VIN pin.

What is the minimum input voltage required for stable operation?

The datasheet specifies a minimum dropout voltage, requiring VIN to be slightly higher than VOUT plus the dropout margin for regulation.
