Pinout
1. Reference (R): This pin is connected to the reference voltage. It is used to set the output voltage through an external resistor network.
2. Anode (A): This pin is usually connected to the ground (or a low voltage point in the circuit). It serves as the common or ground reference point.
3. Cathode (K): This pin is connected to the input voltage. It is where the current flows out of the device, regulating the output voltage as required.
The TL431 is widely used for voltage regulation applications, functioning similar to a Zener diode, but with more precise control over the output voltage through external resistors.
