Voltage regulators play an essential function in a wide range of electronic systems, controlling the voltage that is supplied to the various electrical components. Linear voltage regulators are the most common type of voltage regulator, serving as a simple and reliable form of voltage regulation. The RT9013-26GB is a low dropout linear voltage regulator made by Richtek that is optimized for low current and mobile consumer applications.

Overview

The RT9013-26GB is an adjustable-output linear voltage regulator with a wide operating voltage range of up to 26V. It has a low dropout voltage of only 0.22V, ensuring that it can provide a reliable source of voltage even when the input voltage is only slightly higher than the output voltage. This makes it ideal for battery-powered applications, where the input voltage is constantly fluctuating.

The RT9013-26GB features a typical ground pin current of only 2.5μA, allowing it to deliver a high efficiency performance even at low currents. In addition, the device has an adjustable voltage to allow the output voltage to be set to any value within its specified range. This makes it suitable for a wide range of applications from consumer electronics to automotive systems.

The low ground pin current makes it well suited to applications that require a high efficiency performance, while the adjustable voltage feature makes it suitable for applications with varying voltage requirements.

Working Principle

The RT9013-26GB is a linear voltage regulator and works on the principle of linear voltage regulation. When the input voltage is above the output voltage, the device provides a path for current to flow from the input to the output, allowing the output voltage to be regulated. This process is called a voltage drop, and is represented by the dropout voltage of the device – in this case, 0.22V.

The device also features a number of other features that help to ensure a reliable and accurate output voltage. These features include a high PSRR, low thermal shutdown threshold, and voltage tracking for improved accuracy and stability. These features allow the device to quickly and accurately detect and respond to fluctuations in input voltage.

Conclusion

The RT9013-26GB is a low dropout linear voltage regulator made by Richtek that is optimized for low current and mobile consumer applications. It features a wide operating voltage range of up to 26V, a low dropout voltage of 0.22V, and typical ground pin current of 2.5μA. It also offers an adjustable voltage feature to help meet a variety of voltage requirements. The RT9013-26GB is ideal for applications such as consumer electronics, automotive systems, and battery-powered devices.
