Introduction

PMIC is an abbreviation for power management integrated circuit, which is a type of integrated circuit designed to provide power management functions and voltage regulators. Voltage regulators are designed to regulate the output voltage of a load. The most commonly known type of voltage regulator is the linear voltage regulator, which is the focus of this article. Linear voltage regulators are used in a wide range of applications, such as consumer electronics and industrial control systems. The MPQ2019GN-5 is a linear voltage regulator from the Chinese company MPS. This article will discuss the application field and working principle of the MPQ2019GN-5.

Application field

The MPQ2019GN-5 is suitable for a variety of applications. It is a low dropout voltage regulator with an operating voltage range from 4.5 V to 24 V. This makes it ideal for applications that require a low voltage drop such as LCD TVs and automotive applications.

It is also a high-efficiency voltage regulator, with an efficiency up to 95%. This makes it suitable for applications where saving energy is important, such as LED lighting and mobile phones.
