Pinout
1. Reference (Ref): This pin is used to set the reference voltage. By connecting it to a voltage divider, you can adjust the output voltage.
2. Anode (A): This is the pin where the current flows out. It is typically connected to the ground or the negative supply voltage.
3. Cathode (K): This pin acts as the output of the regulator, and it is where the current flows in. The cathode is connected to a load to maintain a stable voltage.
The TL431 can be used for precise voltage regulation and can be adjusted to output voltages from 2.5V to 36V depending on the configuration of external resistors. It is widely used in power supply circuits for its versatility and precision.
