Voltage Reference Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when ordering. Confirm that the 'AC' grade designation corresponds to the commercial temperature range (0°C to 70°C) rather than the industrial range. Ensure the required output capacitance meets the datasheet specifications for stable operation.

Voltage Reference Selection Notes

Select this part when a fixed 3V reference is needed with high precision in a compact surface-mount package. Consider the AC grade if the application environment remains within the commercial temperature limits. Evaluate the 5mA output drive capability against the load requirements of the connected circuitry.
