PQ015EH02ZZ

The PQ015EH02ZZ is classified as a linear voltage regulator, which is often placed in the PMIC (Power Management Integrated Circuit) group. A linear voltage regulator is a major function integrated circuit that is designed to supply a regulated voltage and current at proper levels to electronic circuits or components. It is important in maintaining a consistent output voltage and is usually used when minimal changes to voltage and current levels are required.

The PQ015EH02ZZ is mostly used as an automotive pre-regulator and can be used in numerous applications. It has a maximum output voltage of 28V, current up to 2A, and a dropout voltage of 0.25V. A few applications where the PQ015EH02ZZ performs well include Battery Management Systems, Automotive cameras, Electrochemical sensors, and Portable electronics.

To understand the PQ015EH02ZZ working principle, it is important to know the differences between linear and switched-mode regulators. Linear voltage regulators operate in linear mode, that is, a voltage is maintained from the output independent from the load. This occurs as the voltage regulator\'s output adjusts itself using the base-emitter junction of a transistor as a variable resistor, manipulating the amount of current that passes through it, so that the output voltage is constant.

On the other hand, a Switched-mode voltage regulator works in a way that its controller constantly adjusts the switching frequency of an on/off switch according to its output voltage. This is done by measuring the feedback voltage and keeping the output voltage at its desired value.

The PQ015EH02ZZ works by utilizing a linear voltage regulation configuration. This means that the circuit consumes power proportional to the amount of current it is outputting. Additionally, the linear voltage regulator must be able to handle any load current needed to maintain the desired output.

The PQ015EH02ZZ voltage regulator is an ideal device for automotive pre-regulator applications due to its ability to maintain a consistent output voltage and current level. The linear mode configuration of the PQ015EH02ZZ helps reduce power consumption and keeps the circuit from heating up. The low dropout voltage and high current allows the device to be used in a wide range of battery powered electronics. This makes the PQ015EH02ZZ a great component for a variety of applications.
