Working Principle of the TL431B:
The TL431BILPE3 voltage reference utilizes a two-stage regulation loop to keep the output stable over varying line and load conditions. The first stage of regulation is a voltage reference circuit consisting of a resistor network and a Zener diode. The Zener diode is biased by a fixed reference current, while the resistors set the output voltage to the desired value. The second stage of regulation uses a voltage feedback loop. This loop monitors the output voltage and adjusts its reference current accordingly, thus maintaining a constant output voltage.

The TL431BILPE3 is a very versatile voltage reference device and is capable of providing excellent performance in a wide range of applications. It can be used in most applications requiring a regulated output voltage, including switching power supplies, DC-DC converters, battery management systems, and more.
