Pinout
1. Reference (REF): This pin is used to set the output voltage by connecting it through a resistor network.
2. Anode (A): This is the input pin that connects to the lower potential of the circuit (usually connected to ground or a negative voltage).
3. Cathode (K): This pin acts as the output and is connected to the higher potential, controlling the current flow through the device.
The LM431 functions as a precision voltage reference with an adjustable output voltage range. It is similar to a Zener diode but allows for more precise voltage regulation through external resistors connected to the REF pin. This makes it useful for applications requiring precise voltage control and regulation in power supplies and other electronic circuits.
