AP7361-12FGE-7 Application Field and Working Principle

AP7361-12FGE-7 is a linear voltage regulator from PMIC (Power Management IC). This linear voltage regulator plays an important role in regulating the output voltage, which is necessary for helping digital circuits properly work. This article discusses the general applications of AP7361-12FGE-7, its working principle and other components necessary for its installation.

Applications

AP7361-12FGE-7 voltage regulator is mostly used in automotive, commercial and industrial applications. The voltage regulator can be used to provide a regulated output voltage of 12V and can provide a maximum current of 3A to devices that need a constant and reliable power supply. It is suitable for applications like cellular radio transmitters, microcontroller-based projects, regulated power supplies, and communication systems.

Working Principle

The AP7361-12FGE-7 voltage regulator uses a power steady-state reference voltage and a feedback loop to regulate the output voltage and withstand line voltage variances. The power steady-state reference voltage is the reference point that the desired output voltage is compared to in order to adjust it. When the output voltage deviates from the set reference voltage input, the voltage regulation loop attempts to bring the output voltage back towards this reference. This is what helps keep the output voltage at a steady state and not fluctuate too widely.

The voltage regulator also uses a buck-boost switching regulator that works in conjunction with the linear regulator. The buck-boost regulator is responsible for supplying the current and adjusting the output voltage by using a transformer to increase or decrease the amount of voltage output. The buck-boost regulator is also responsible for regulating the voltage for higher and lower input voltages and can handle input voltages from 6V to 18V.

Components Necessary for Installation

Besides the voltage regulator, there are a few extra components necessary for the installation of the AP7361-12FGE-7. This includes a backlight driver, a transistor, capacitors, resistors, and an inductor. All of these components are necessary to help regulate the voltage input and make the output more consistent and reliable.

Besides these components, the voltage regulator also requires a heatsink, as it can produce some heat of it is under a great load. Without a heatsink, the regulator could overheat and damage the device it is being used for.

Conclusion

In conclusion, the AP7361-12FGE-7 is a linear voltage regulator from PMIC used to regulate the output voltage from digital circuits. The voltage regulator comes with a buck-boost switching regulator which helps regulate a wide range of voltage inputs from 6V to 18V. Additionally, the AP7361-12FGE-7 is suitable for automotive, commercial, and industrial applications and can provide a output of 12V with a maximum current of 3A. For the installation of the voltage regulator, it is necessary to include extra components including backlight driver, a transistor, capacitors, resistors, and an inductor. Lastly, it is important to use a heat sink as the voltage regulator can produce heat under higher loads.
