Procurement Notes

Verify the specific suffix QDBVR corresponds to the automotive grade qualification and SOT-23-6 package configuration required for your design. Confirm that the 5.0V output variant matches your system requirements, as the REF35 family offers multiple voltage options. Ensure compatibility with your PCB layout guidelines regarding the EN and NR pin connections to maintain specified noise and power performance levels.

Selection Notes

Select this component when designing portable or battery-powered instrumentation requiring minimal standby current without sacrificing precision. The wide operating temperature range makes it suitable for industrial environments. Consider the available output capacitor range and the need for external filtering on the NR pin if low-frequency noise specifications are critical for your data converter or sensor interface.
