Introduction

RT9011-MMGQW is a linear voltage regulator that belongs to the PMIC (Power Management Integrated Circuit) family. It was developed for consumer electronics designs, including smartphones and portable devices, to provide energy savings and improve system efficiency. The RT9011-MMGQW linear regulator supports 1.5 A/2.2 A of output current and up to 10 V of output voltage. The RT9011-MMGQW provides fast transient response and excellent line and load regulations, allowing designers to deliver good product performance with high efficiency and reliability.

Application Field

RT9011-MMGQW is designed to regulate the output voltage, making it suitable for a wide range of consumer electronic applications. It is especially useful when power efficiency and system power savings are required. It is suitable for use in applications like wireless handsets or mobile communication products, as well as home entertainment equipment and industrial use. Its excellent line and load regulation and low power consumption make it ideal for applications where low power is essential, such as ultra-low power remote sensors, clocks, and dataloggers.

Working Principle

The RT9011-MMGQW linear voltage regulator works by providing a stable, regulated output voltage from a variable input voltage. It does this by using a series of 6 external P-MOSFETs. When the input voltage is higher than the output voltage, these 6 MOSFETs are turned on in series as a voltage regulator. When the input voltage rises, the additional energy not needed is absorbed by the switched-on transistors, resulting in a constant output voltage. The regulate voltage is adjusted by changing the resistance of the resistors connected to 2 of the MOSFETs.

Features

The RT9011-MMGQW features a fast transient response, with a maximum load current of 1.5 A/2.2A and a maximum output voltage of 10 V. It has an adjustable output voltage from 0.7 V to 10 V, and its output voltage is accurate to within 0.5% across variations in temperature and line/load conditions. The RT9011-MMGQW also has an integrated power-on reset circuit, which ensures clean power up of the output and prevents overshooting. It is also designed with a low quiescent current, allowing it to maintain excellent power efficiency in low-power applications.

Conclusion

The RT9011-MMGQW is a linear voltage regulator designed to provide a stable, regulated output voltage from a variable input voltage. It is suitable for use in applications such as smartphones, home entertainment equipment, and low power devices, as it is designed with low power consumption and excellent line and load regulation. The RT9011-MMGQW is also designed with a fast transient response and is accurate to within 0.5%. With its wide range of features, the RT9011-MMGQW is a great choice for designers needing a highly efficient and reliable voltage regulator.
