It provides a 2.495 V reference with ±0.5% tolerance and can sink up to 100 mA, making it suitable for precision regulation in ECU power supplies, sensor bias circuits, and on-board charger feedback loops.
The ±0.5% tolerance (B-grade) is tighter than the standard TL431's ±2.2%, which matters when the reference sets the output accuracy of a switching regulator or an ADC reference.
Yes, the TL431BQDBZRQ1 is part of the Automotive, AEC-Q100 series, qualified for automotive-grade applications including under-hood and chassis domains.
The TL431BQDBZRQ1 offers ±0.5% tolerance on the 2.495 V reference voltage, which is the B-grade precision level in the TL431 family.
The TL431BQDBZRQ1 can sink up to 100 mA as a shunt regulator, limited by the SOT-23-3 package thermal capability.
