Pinout
The TLV431IDBZR is a precision adjustable shunt voltage reference, typically used in control and monitoring applications. It is packaged in a SOT-23-3 configuration, which means it has 3 pins. Here is a concise breakdown of its pin functions:
1. Pin 1 (Reference, Ref): This pin is used for setting the reference voltage. By connecting external resistors, you can adjust the output voltage to a desired level.
2. Pin 2 (Anode): The anode is the ground or negative supply pin, serving as the common return path for current flowing through the TLV431IDBZR.
3. Pin 3 (Cathode, Vout): This is the output pin (also the cathode) where the regulated voltage is maintained. It sinks current to maintain a stable reference voltage across the Ref and Anode pins.
This device is often used for voltage regulation, voltage monitoring, and as a comparator with a reference.
