Working Principles

The ZR431LF02TC is a precision shunt regulator that maintains a stable output voltage by comparing the reference voltage at the cathode pin with an adjustable voltage set by an external resistor. When the load voltage exceeds the desired value, the ZR431LF02TC shunts current from the cathode to the anode, regulating the output voltage. Conversely, when the load voltage drops below the desired value, the shunting action decreases, allowing more current to flow through the load.
