MPQ2013GQ-P Application Field and Working Principle

PMIC - Voltage Regulators - Linear are critical components in product designs, providing the right voltage control performance in order to maintain the reliability and stability of the product. In this article, we will discuss the applications, as well as its working principle, of the MPQ2013GQ-P linear voltage regulator.

Applications of MPQ2013GQ-P

The MPQ2013GQ-P linear voltage regulator is a three-pin, surface mount, adjustable voltage regulator that operates with a small external sense resistor. It has a wide input voltage range of up to 16V and a wide output voltage range from 0.8V to 20V. This makes it ideal for a variety of applications, such as post regulation, on-card regulation, as well as replace linear regulators such as LDOs or low dropout (LDO) regulators.

For instance, the MPQ2013GQ-P is ideal for desktop and notebook computer systems, wireless local area networks (WLANs), and chip-sets due to its ability to regulate an input voltage with accuracy and an exceptionally high output voltage ripple rejection. It is also suitable for many other applications with medium power requirements such as telecommunications, instrumentation, automotive systems, and consumer electronics.

Working Principle of MPQ2013GQ-P

The MPQ2013GQ-P is a low-power linear voltage regulator, which combines a voltage reference, an error amplifier, and a series pass element. It works by taking the input voltage and using a sense resistor to measure the voltage across the pass transistor to hold the output voltage at the predetermined level.

First, the voltage at the output of the reference is compared to the voltage at the output of the regulation loop. The resulting error voltage controls the current in the pass transistor, which adjusts the output voltage accordingly. In this way, the MPQ2013GQ-P is able to maintain a regulated output voltage even when the input fluctuates.

The MPQ2013GQ-P also comes with a slew rate control feature, which allows the output voltage to be adjusted more precisely and rapidly. This feature also reduces output voltage ripple, which can affect system performance. In addition, the MPQ2013GQ-P comes with foldback current limiting, which protects it from over-current conditions.

Conclusion

In conclusion, the MPQ2013GQ-P linear voltage regulator is an ideal solution for a wide range of applications where precision and reliability are required. Its wide input and output voltage range and slew rate control features enable it to provide accurate and stable voltage control, while its foldback current limiting feature helps to protect it from over-current conditions.
