The ZN460CP is a monolithic integrated circuit manufactured by Plessey that is used as a voltage regulator. It is designed to provide an adjustable and stable power supply for loads up to 1A with a constant voltage accuracy of 0.5%. This voltage regulator features a wide range of input voltage from 3V up to 25V. It also incorporates over-temperature protection and reverse polarity bias protection. Additionally, the ZN460CP features low power consumption and allows for both 5V and 12V voltage outputs. It also has two external capacitance selection pins, allowing different capacitance values to be chosen depending on load conditions.
