The PQ1R18 functions as a current regulator, providing excellent line and load regulation with high efficiency and low EMI. The device can operate as a standalone low-voltage regulator, or as part of a system where it can be used in multiple applications such as laptops, power supplies, and portable electronics.Application
The PQ1R18 linear voltage regulator is suitable for a wide array of applications. It can be used in laptop power supplies for powering various components including monitors, hard drives, and processors. It can also be used in power supplies for electronics such as adapters and chargers, as well as in a variety of other applications such as cameras and handheld devices. The regulator is also used in automotive electronics such as air conditioning systems and power seat control.Working Principle
The PQ1R18 linear voltage regulator operates on the principle of voltage regulation using two resistors in series, which are connected to both the input and output voltage. The regulator maintains an output voltage by diverting excess current to a compensating resistance, which is connected to the reference voltage terminal. The regulator is capable of maintaining precise and stable output voltage under varying conditions.The regulator works by comparing the input voltage with the reference voltage and automatically adjusting the series resistors to maintain the desired output voltage. This ensures that the output voltage remains within a specified range despite changes in the input or load. The regulator also offers over-voltage protection, short-circuit protection, and thermal shutdown for improved protection of the system.Conclusion
The PQ1R18 linear voltage regulator is a highly reliable and efficient solution for power regulation in a variety of applications. It offers excellent line and load regulation and is suitable for a range of voltages from 1.2V to 18V. The regulator is also capable of providing superior protection against overloads, shorts, and thermal shutdowns. This makes it an ideal choice for laptop power supplies and other applications.
