PMIC (Power Management Integrated Circuit) is a single chip that typically provides all the necessary functions for a complete system power management solution. Voltage regulators are one of the essential functions of PMICs to control and maintain a certain voltage output. Linear voltage regulators are the simplest and oldest form of voltage regulation. PQ015EZ02ZZH is a linear voltage regulator integrated circuit (IC) which can be used in various applications to maintain an output voltage within a narrow range. This article will discuss the application fields of PQ015EZ02ZZH and its working principle.

Applications

PQ015EZ02ZZH can be used in many different fields, such as automotive and industrial applications. In automotive applications, PQ015EZ02ZZH can be used in electronic control units (ECU), powertrain control system, light and sound control, autonomous and semi-autonomous systems, and active safety systems. PQ015EZ02ZZH also has a wide range of usage in industrial application, such as in industrial robots, embedded controllers, computer and networking systems, industrial telecommunication systems, active medical devices, and in-flight entertainment systems. In all of these applications, PQ015EZ02ZZH can be used to regulate the output voltage and provide constant voltage to the system’s microprocessors and other components.

Working Principle

The PQ015EZ02ZZH linear voltage regulator works on the basic principle of stabilizing the voltage output. It has two components: the control element and the series element. The control element is a voltage reference device, which has a fixed output voltage. This voltage is used to control the series element. The series element is used to regulate the voltage output of the regulator. It consists of a power transistor. The power transistor has two inputs, the control voltage and the sensed voltage, and one output – the regulated output voltage.

The sensed voltage is the voltage that is to be regulated by the regulator. This voltage passes through the power transistor and is compared with the control voltage. If the sensed voltage is higher than the control voltage, then the power transistor will conduct less current, thus lowering the output voltage. Conversely, if the sensed voltage is lower than the control voltage, then the power transistor will conduct more current, thus increasing the output voltage. This simple principle is what makes PQ015EZ02ZZH linear voltage regulator a reliable and efficient voltage regulator.

Conclusion

PQ015EZ02ZZH is a linear voltage regulator integrated circuit (IC) which can be used in various applications to maintain an output voltage within a narrow range. Its wide range of applications in automotive and industrial fields makes it a popular choice for many systems. The working principle of PQ015EZ02ZZH is based on controlling the output voltage considering the control and sensed voltage inputs. This simple, yet reliable regulation makes PQ015EZ02ZZH a preferred choice of many projects.
