PQ7DV10B, which belongs to the category of PMIC—Voltage Regulators—Linear, is a monolithic integrated circuit designed to regulate a fixed voltage output with an accuracy of ± 2.5%.

The principal application of the PQ7DV10B is to provide an adjustable level of output voltage that is stable, reliable and accurate. It can be used in a variety of applications, including cellular phones, notebook computers, and other general purpose voltage regulation applications. The main features of the PQ7DV10B include an input voltage range of 2.85 to 18V, a 0.6% line regulation, and a 0.1% load regulation.

The PQ7DV10B works by regulating the output voltage of an external power supply. It does this by controlling the flow of current that passes through a series of resistors. The amount of current that passes through each of the resistors is determined by the voltage of an external reference voltage. The external reference voltage is applied to an amplifier, which then controls the flow of current through the resistor network. As the reference voltage increases, the amount of current decreases, and the voltage output of the power supply decreases.

The PQ7DV10B uses a variety of techniques to ensure that the output voltage remains stable despite any changes to the input voltage, load or temperature changes. These techniques include using advanced compensation techniques, using very high-precision passives and controlling the amount of current that passes through the precision resistors. The combination of these techniques provides a very accurate, stable and reliable output voltage.

To protect the PQ7DV10B from damage caused by excessive input current, it is equipped with integrated over-current protection and under-voltage lockout. This ensures that the PQ7DV10B stays within its safe operating limits. In addition, the PQ7DV10B has an integrated thermal shutdown circuit that prevents the device from overheating due to overloading.

The PQ7DV10B also includes an extra feature that allows for remote sensing. This means that the output voltage can be adjusted remotely, without the need for additional external components. The remote sensing feature improves the accuracy of the output voltage, as it compensates for voltage drops in the power connections.

In summary, the PQ7DV10B provides excellent voltage regulation performance, with accurate and stable output voltage, wide input voltage range and integrated over-current protection and thermal shutdown. It is versatile and can be used in a variety of applications, including mobile phones, notebooks, industrial applications and general purpose voltage regulation. The remote sensing feature is a useful extra feature that allows for precise voltage adjustment without the need for external components. Overall, the PQ7DV10B is an excellent device for voltage regulation applications.
