Product details

Precision 3 V reference for automotive and industrial analog chains

The Texas Instruments REF4132B30DBVRQ1 is a 3 V fixed-output series voltage reference qualified to AEC-Q100, making it a direct fit for automotive ECU, ADAS sensor bias, and battery-management analog front-ends that demand a stable, low-noise rail over the full -40°C to 125°C temperature range. Initial output tolerance is ±0.05%, and the temperature coefficient is 30 ppm/°C. Input voltage range is 3.05 V to 5.5 V. Output current is rated for 10 mA. Supply current is 100 µA typical — a low quiescent draw that matters in always-on automotive modules where every microamp counts against the sleep-mode budget.

The SOT-23-5 footprint is forgiving; you can hand-solder a replacement with fine tweezers.

Frequently asked questions

Will REF4132B30DBVRQ1 drop into a board that was specified around LM4132AMF-4.1/NOPB without rewiring?

No — the LM4132AMF-4.1/NOPB outputs 4.096 V, while the REF4132B30DBVRQ1 outputs a fixed 3 V. The pinout is the same SOT-23-5, but the voltage difference means the board's reference rail and any downstream ADC scaling would need to be re-evaluated. They are not drop-in replacements.
