The ZR285Y02 operates as a shunt regulator, meaning that it regulates the voltage by shunting excess current to ground. It requires an external resistor to limit the current flowing through the regulator. The output voltage is determined by the internal reference voltage and is highly stable and accurate. The low temperature coefficient ensures that the output voltage remains relatively constant over a wide range of temperatures. The regulator's low output impedance ensures that the output voltage remains stable even when the load current changes. This device is ideal for applications requiring a high-performance, cost-effective voltage reference.
