Frequently Asked Questions
Is the REF3033AIDBZRQ1 AEC-Q100 qualified for automotive applications?
Yes, the REF3033AIDBZRQ1 carries the RQ1 suffix indicating AEC-Q100 automotive qualification, making it suitable for use in automotive-grade electronic control units, ADAS modules, and other in-vehicle electronics where component reliability certification is a design requirement for functional safety compliance.
What input voltage range does the REF3033AIDBZRQ1 support?
The REF3033AIDBZRQ1 requires an input voltage of at least 3.301V and up to 5.5V for normal operation, with an absolute maximum of 7V. This makes it well suited for use on a 5V automotive supply rail, providing a regulated 3.3V reference output with approximately 1.7V of headroom over the output voltage.
What package is the REF3033AIDBZRQ1 offered in?
The REF3033AIDBZRQ1 is housed in a 3-pin SOT-23 package (JESD-30 R-PDSO-G3), one of the most compact SMT packages available. This tiny footprint minimizes board area consumption in space-constrained automotive ECU designs where dozens of components must coexist on small multilayer PCBs within sealed electronic modules.
What output voltage does the REF3033AIDBZRQ1 provide?
The REF3033AIDBZRQ1 provides a fixed 3.3V precision reference output. The 'I' grade suffix and 'AI' designation specify industrial and automotive temperature performance respectively, ensuring the 3.3V output remains stable and accurate across the full operating temperature range required for automotive-qualified designs.
