The TLV431 is a low-voltage 3-terminal adjustable voltage reference with specified thermal stability over applicable industrial and commercial temperature ranges.
The TLV431 is a low‑voltage three‑terminal adjustable voltage reference designed for industrial and commercial temperature ranges. Output voltage is set by two external resistors and can be adjusted anywhere between 1.24 V and 6 V, making it suitable for on‑board regulation and isolated feedback circuits.
The datasheet provides ordering information for multiple package options (SC‑70, SOT‑23‑5, SOT‑23‑3, TO‑92, etc.), absolute maximum ratings, electrical characteristics such as reference voltage tolerance, temperature drift, output impedance, and minimum cathode current, as well as mechanical dimensions and packaging details.
