The reference is built around a bandgap circuit with a typical temperature coefficient suited for industrial temperature spans.
Initial tolerance is ±2.2% at 25 °C, which defines the worst-case output voltage window for the divider network. The device can sink up to 100 mA continuous, limited by package dissipation in the SC-70-6.
The SC-70-6 package (also designated SOT-363) keeps the footprint small for dense layouts.
The TL431QDCKT has an initial tolerance of ±2.2% at 25 °C. This sets the accuracy of the output voltage set by the external resistor divider.
The TL431QDCKT is a specific grade of the TL431 family. The TL431B typically offers a tighter tolerance (e.g., ±0.5%), but both are adjustable shunt references with the same functional pinout and operating range. The QDCKT suffix indicates the SC-70-6 package. For a drop-in replacement, confirm the tolerance grade your design requires.
