Pinout
1. Reference Pin (Ref): This pin is used to set the reference voltage. By connecting it to a resistor divider, you can adjust the output voltage.
2. Anode Pin (A): This is the cathode of the internal reference and the ground of the device. It acts as the ground or the negative terminal in the circuit.
3. Cathode Pin (K): This pin functions as the output of the shunt regulator. It connects to the load and provides a stable reference voltage by shunting current to ground.
The TL431 can provide an output voltage that is adjustable over a range of 2.5V to 36V, with a typical initial accuracy of 0.5%. It is commonly used in applications like voltage monitoring, voltage reference, or as a comparator.
