That ±0.5% is the spec that decides whether your ADC reference, power supply feedback divider, or comparator threshold stays within budget across temperature and load. The 100 mA output current capability means it can sink enough current to bias an optocoupler LED or power a small load directly, not just sit as a passive reference. ## Industrial temperature range — no derating needed The 700 µA minimum cathode current keeps the reference biased even in low-power sleep modes. ## SC-70-6 footprint for tight boards No last-time-buy math needed for new designs.","metaTitle":"TL431BQDCKR Shunt Reference, ±0.5% Tolerance, SC-70-6","metaDescription":"Texas Instruments TL431BQDCKR adjustable shunt reference, ±0.5% tolerance, 100 mA output, -40°C to 125°C.
