Product Overview
REF3030AIDBZR is the 3.0 V member of TI’s REF30 low-power reference family. It targets portable and loop-powered circuits where quiescent current and package size matter more than the ultra-low drift of larger precision references.
TI now groups this order code under the REF30 family; the older REF3030-specific datasheet URL has been retired. HKEQGOO therefore uses the live REF30 datasheet and product family so the engineering link does not resolve to a 404 page.
The AIDBZR order code is the standard REF30 grade in a 3-pin SOT-23, supplied on a 3000-piece reel. It should not be confused with the newer REF30E enhanced grade, which has tighter drift/accuracy specifications.

Functional Highlights
Low operating current suits always-on reference rails
A tens-of-microamps reference can remain powered in battery or 4–20 mA transmitter electronics without consuming a large share of the system budget.
Standard and enhanced REF30 grades are not interchangeable on precision claims
REF30E improves drift and initial accuracy; using those headline numbers for REF3030AIDBZR would overstate this exact standard-grade order code.
Design Considerations
- Use the standard-grade REF30 accuracy/drift values for this exact AIDBZR part.
- Keep the reference output isolated from pulsed digital or converter loads that could modulate the output.
- Treat the updated REF30 family URL as authoritative for future revision checks.
