PQ070VK02FZH Application Field and Working Principle The PQ070VK02FZH is a Linear Voltage Regulator integrated circuit belonging to the family of PMIC (Power Management Integrated Circuits). PMIC is an integral part of a large range of electronic products and implements power-management functions using integrated circuits. This particular integrated circuit is used primarily to provide a steady voltage source to electronic components, such as CPUs, microprocessors, batteries, and AC-DC converters.In terms of operation and working principle, the PQ070VK02FZH takes in a higher voltage at its input, and then reduces this voltage as required and outputs it at the correct rate. It does this by using an internal voltage reference to control the output current through an internal ( usually BJT ) power transistor. The output voltage is then regulated by turning on and off the output according to the input voltage.The PQ070VK02FZH is capable of providing a steady output of up to 0.4A of current at voltages ranging from 4V to 32V. The maximum power dissipation of up to 10 watts allows for the use of multiple outputs in applications requiring a higher current load. Also, the PQ070VK02FZH has a functionality of Soft Start and Overcurrent protection, making it more suitable for applications requiring high reliability and safety.The PQ070VK02FZH is mainly used in home electronics and consumer goods such as TVs, computers, and portable electronics. Its small size and wide input voltage range make it an ideal choice for these types of goods. Other application areas of the PQ070VK02FZH include industrial control, battery operated systems, and power supplies for printers, modems, and imaging systems.Since the PQ070VK02FZH is a linear voltage regulator, the output can only be the same as the input voltage or slightly lower than the input. This limitation makes it unsuitable for use in applications requiring a greater range of voltage output. For this reason, it is often used in combination with a switching mode regulator to provide increased range of output voltage and to protect the circuit from overvoltage, undervoltage and over-current.Overall, the PQ070VK02FZH is a linear voltage regulator circuit suitable for a variety of applications requiring a stable and reliable power source. With its small size, wide input voltage range and integrated protection features, it is the ideal choice for many home and office applications.
