(Pack of 5) TL431 Adjustable Precision Shunt Regulator TO 92 Package

(Pack of 5) TL431 Adjustable Precision Shunt Regulator TO 92 Package

The TL431 is a high-precision adjustable shunt voltage regulator that functions like a programmable Zener diode. It features a 2.5V precision reference and can be configured to regulate voltages up to 36V using an external resistor divider. Because of its high accuracy, good temperature stability, and fast response, it is widely used in power supplies, SMPS feedback circuits, and voltage reference applications.

This product is supplied as a pack of 5 pieces in the TO-92 through-hole package, making it ideal for prototyping, repairs, production, and hobby projects. The TO-92 package allows easy manual soldering and breadboard-friendly use.
