Product Description

The TL431A is a three-terminal adjustable shunt regulator with excellent temperature stability.

The device has a typical dynamic output impedance of 0.2 Ω and can be used to replace Zener diodes in many applications.

Its key features include: an adjustable output voltage up to 36 V; low dynamic output impedance (typical value of 0.2 Ω); a current‑capture capability ranging from 1 to 100 mA; low output noise voltage; rapid turn‑on response; and effective temperature compensation across the operating temperature range.

The typical value of the equivalent temperature coefficient across the entire temperature range is 50 ppm/°C.

This device is suitable for applications such as shunt regulators, high‑current shunt regulators, and precision current limiters.

The package type is SOT-23.
