Working Principles

The TLV431CDBVTE4 is a precision shunt regulator that uses a bandgap reference to generate a stable output voltage. It operates by comparing the reference voltage with an adjustable voltage divider formed by external resistors connected to the REF pin. The internal circuitry then adjusts the cathode current to maintain a constant voltage at the reference pin.
