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.
Package and mounting
The SOT-23-5 footprint is forgiving; you can hand-solder a replacement with fine tweezers.
Lifecycle and sourcing
This part is listed as Active and ROHS3 Compliant. No end-of-life notice or last-time-buy window has been issued.
