Additional Details:

The NJM1431AU(TE2) functions as a shunt regulator, meaning it regulates voltage by shunting excess current to ground. The output voltage is adjustable by using external resistors, allowing for precise control over the regulated voltage. The reference voltage and cathode voltage are key parameters, which are specified in the NJR datasheet. It is commonly used in feedback circuits for power supplies, providing a stable and adjustable voltage reference for regulation. The device requires a minimum cathode current to maintain regulation, and the datasheet specifies this parameter. Proper thermal management may be necessary in high-current applications. The (TE2) suffix indicates the specific surface-mount package. It is important to follow the manufacturer's recommendations for PCB layout and soldering to ensure reliable performance. The device offers excellent line and load regulation, meaning the output voltage remains stable despite variations in input voltage and load current. Its low temperature coefficient ensures the output voltage remains stable across a wide range of operating temperatures. Detailed specifications on voltage accuracy, temperature stability, and load regulation can be found in the datasheet.
