What this shunt reference does on your rail
It sinks up to 15 mA of cathode current and draws only 80 µA minimum to stay in regulation, making it a fit for low-power feedback loops, bias supplies, and precision comparator thresholds. The ±1% tolerance on the reference voltage is tighter than the standard TLV431 grade, which matters when the reference sets the accuracy of an ADC reference input or the regulation point of an isolated flyback converter.
The output can be programmed from 1.24V up to 6V maximum using a resistor divider from cathode to reference pin. The 6V ceiling limits this part to low-voltage rails — it will not generate a 10V bias, so if your design needs a higher reference, step up to the TL431 family.
Supplied in Tape & Reel, consistent with volume pick-and-place requirements.
