Pinout
The TL431BQDBZRQ1 is a three-pin adjustable precision shunt regulator. It typically comes in a SOT-23 package, which includes the following pins:
1. Anode (A): This is the input pin that connects to the lower potential or ground side of the circuit.
2. Cathode (K): This pin is connected to the higher potential in the circuit and typically acts as the output terminal. It conducts current when the device is regulating, maintaining a constant voltage across the reference and cathode.
3. Reference (R): This pin is used to set the desired output voltage by connecting it to a resistor network. The voltage at this pin determines when the shunt regulator will start conducting, based on the internal reference voltage.
The TL431BQDBZRQ1 is commonly used to provide a stable reference voltage in power supply circuits and voltage monitoring applications. It offers adjustable output voltages ranging from 2.5V to 36V, determined by external resistor components.
