Pinout
Here’s a brief overview of its pin functions:
1. Reference (R): This pin is used to set the reference voltage. The reference pin is connected to the non-inverting input of the internal op-amp.
2. Anode (A): This is the terminal where the current flows out of the device. It is typically connected to the ground or a negative voltage in a circuit.
3. Cathode (K): This pin is the output terminal of the device and is used to provide regulated output voltage. It is connected to the inverting input of the internal op-amp.
The TL431AQDBZRQ1 can be used for precision voltage reference and regulation applications due to its adjustable output voltage capability, which is set using external resistors.
