The minimum cathode current is 100 µA, so the bias resistor value stays reasonable even at low supply voltages. It is not AEC-Q100 qualified, so skip it for under-hood automotive or 125°C environments.","metaTitle":"TLV431BIDCKR shunt reference, adjustable 1.24 V to 6 V","metaDescription":"Texas Instruments TLV431BIDCKR low-voltage adjustable shunt reference.
