TL431 Adjustable Shunt Regulator SOT-23

TL431 Adjustable Shunt Regulator SOT-23 is a precision three-terminal device designed for voltage and current referencing applications. It provides an adjustable output voltage from 2.5V to 36V using two external resistors, making it a reliable alternative to Zener diodes. With low output noise, excellent thermal stability, and a sink current range of 1mA to 100mA, this regulator is widely used in power electronics, embedded systems, and industrial automation.

This voltage reference IC is commonly found in switch-mode power supplies (SMPS), battery management systems, secondary-side regulation, and voltage monitoring circuits. Its low temperature drift (6mV typical) and low output impedance (0.2 ohm) ensure stable and efficient operation even in demanding environments. The SOT-23 package makes it ideal for compact PCB designs, offering versatility in applications such as voltage comparators and feedback loops in power control systems.

Designed for automotive, consumer electronics, and industrial power applications, the TL431 is a cost-effective solution for engineers looking for high-precision voltage regulation.
