ONSEMI LM431ACZX adjustable shunt regulator

The LM431ACZX is a three-terminal adjustable shunt regulator with thermal stability across a wide temperature range. It allows output voltage setting between approximately 2.5 V and 36 V using two external resistors, making it suitable for various applications. Featuring low output noise, fast turn-on response, and low dynamic impedance of 0.2 Ω, it provides reliable voltage regulation. Its thermally stable design and high current sink capability of 1.0 to 100 mA enable it to replace Zener diodes effectively in power regulation circuits. Compact and robust, it suits industrial and consumer electronics.
