{"product_id":"105145","title":"TL431BQDBVR","description":"\u003cp\u003eProgrammable Precision Reference Shunt Regulator (Automotive Grade) manufactured by Texas Instruments. This iconic monolithic three-terminal linear integrated circuit features an advanced internal dynamic bandgap architecture layout housed in a compact surface-mount SOT-23-5 package, with the \"BQ\" code designating factory screening for strict automotive-grade temperature metrics spanning -40°C to 125°C. It functions as a programmable Zener shunt diode whose output voltage baseline can be custom-set to any value between 2.5V and 36V via two external resistors, maintaining an ultra-stable thermal drift profile under extreme under-hood vibration and temperature stress. It is universally deployed inside electric vehicle (EV) battery management systems, automotive electronic control units (ECUs), high-reliability switching power supplies, and precision sensor calibration loops.
