Working Principles

The TL431BVLPRAG is a precision shunt regulator that maintains a stable output voltage regardless of input variations. It operates by comparing the reference voltage at the Reference (R) pin with an external voltage divider network connected to the Anode (A) and Cathode (K) pins. By adjusting the resistors in the voltage divider, the desired output voltage can be set.

When the input voltage exceeds the reference voltage, the TL431BVLPRAG starts conducting current from the Anode to the Cathode, regulating the output voltage. This feedback mechanism ensures a constant output voltage even when the input voltage or load conditions change.
