About this product

The TL431CSF is a three-terminal programmable shunt regulator diode packaged in a compact SOT-23 surface-mount form factor. Renowned for its thermal stability, this integrated circuit functions effectively as a low-temperature coefficient Zener diode.

It allows for programmable output voltage ranges from 2.5V to 36V using two external resistors. Due to its sharp turn-on characteristics and low dynamic output impedance, the TL431 is an excellent replacement for Zener diodes in various applications, including onboard switching power supplies, adjustable voltage sources, and LED drivers.

This SOT-23 version is ideal for space-constrained PCB designs and modern electronics projects requiring precision voltage regulation.
