The 1 mA cathode current keeps the quiescent draw low, making it a fit for precision bias supplies, error amplifiers, and monitoring circuits in industrial control, power supplies, and automotive electronics. The SOT-23-3 footprint matches the industry-standard SC-59 / TO-236-3 land pattern, so no board respin is needed when swapping between similar shunt references. It is ROHS3 compliant, meeting current EU material restrictions. No last-time-buy or obsolescence risk for new designs.","metaTitle":"STMicroelectronics TS2431BILT Shunt Voltage Reference, ±0.5%","metaDescription":"TS2431BILT adjustable shunt voltage reference from STMicroelectronics. ±0.5% tolerance, 100 mA output, -40°C to 105°C.
