MPQ2013AGG-Z is a Linear Voltage Regulator which is applicable to various power electronic applications such as Personal Computers, Network Equipment, Automotive Electronics and LEDs. As a kind of Power Management Integrated Circuits (PMIC), Linear Voltage Regulators are used to convert input voltage signal to a desired output voltage signal, in order to meet the power needs of the connected circuits and devices. In the field of automotive electronics, the MPQ2013AGG-Z can be used to regulate the voltage input to common systems such as LED headlights or taillights, vehicle power windows or audio systems.

Working Principle

The working principle of a linear voltage regulator is simple. The input voltage is compared to a reference voltage and the difference between them is then compared to a second voltage reference. This voltage difference is used to control a pass transistor which, in turn, has a linear relationship between the current flowing through it and the control voltage.

The MPQ2013AGG-Z maintains a fixed voltage output from a varying input voltage, isolating it from any disturbances to the input voltage. It features excellent output voltage accuracy and enables low dropout (LDO) and low quiescent current performance. It also has a high power supply rejection ratio (PSRR) and low output noise, and is capable of driving current up to 2.6A.

The MPQ2013AGG-Z provides protection against overvoltage, overcurrent and thermal overload. An on/off control pin allows the user to turn on or off the device to save power. Once the current exceeds the protection levels, an internal limiter shuts down the device and the output voltage drops. Once the output voltage is below the overvoltage protection threshold, the device will automatically reset and turn on again.

In order to maximize safety and ensure satisfactory performance, the MPQ2013AGG-Z requires a proper enclosure for installation. It is important to use an approved enclosure and to follow the manufacturer’s guidelines for installation.

Conclusion

The MPQ2013AGG-Z is a linear voltage regulator that can be used in various applications to convert input voltage signal to a desired output voltage, while providing excellent output voltage accuracy, high power supply rejection ratio, low output noise, low quiescent current and excellent protection against overvoltage, overcurrent and thermal overload. Installation, however, must include an approved enclosure and should follow the manufacturer’s guidelines.
