TL431 Voltage Reference
The TL431 is a highly versatile and precision adjustable shunt voltage reference, designed to operate over a wide voltage range from 2.495V to 36V. It functions by comparing its feedback voltage to an internal reference and adjusting its cathode current to maintain a stable output, acting as a programmable Zener diode. Widely adopted in power management circuits, it is essential for applications requiring stable and accurate voltage regulation.
