Pinout
The TL431BIDBZR is a precision programmable shunt voltage reference. It is typically available in a 3-pin package, such as SOT-23 or TO-92. The three pins are:
1. Anode (A): This pin is connected to the lower potential side of the voltage to be regulated. It serves as the reference's negative terminal.
2. Cathode (K): This pin is the output and is connected to the higher potential side of the voltage. It functions as the reference's positive terminal and is responsible for the output stabilization.
3. Reference (R): This is the control pin where an external resistor network or voltage divider is connected to set the desired output voltage.
The TL431BIDBZR acts as an adjustable precision shunt regulator, which maintains a stable reference voltage by allowing current to flow through it in a controlled manner. This is widely used in applications such as voltage regulation, switching power supplies, and adjustable power supplies.
