It is part of the RT series from Richtek, which is designed for mobile application and is capable of providing a high-accurate output voltage with low dropout voltage and low quiescent current. It is suitable for battery-powered products, providing a wide working range with a low operating current and low supply voltage.

Application Fields

The RT9078N-33GJ5 is widely used in various applications, especially in high current and low voltage areas such as mobile phones, personal digital assistants (PDAs), smart phones, digital cameras, laptop computers and tablet PCs. It can also be used in other areas, including IoT, automotive and industrial applications.

Working Principle

The RT9078N-33GJ5 operates on the principle of a voltage regulator. It is designed to maintain a steady output voltage by using a reference voltage and comparing it to the output. When the output deviates from the reference, the regulator takes corrective action to bring it back to the required voltage.

The regulation is achieved by using a series of components, such as an error amplifier, reference voltage source, current sense resistors and a power transistor. The error amplifier compares the output voltage with the reference and generates an error signal. The output voltage is then adjusted by the power transistor to maintain a steady voltage.

The RT9078N-33GJ5 also includes additional features to improve its performance, such as short circuit protection, over temperature protection and over-current protection. It also includes internal compensation to ensure stability and accurate output voltage.

Conclusion

The RT9078N-33GJ5 is a low-noise, high-performance linear voltage regulator that is suitable for multiple applications and has a wide working range with a low operating current and low supply voltage. It is designed for mobile applications and is capable of providing a stable and accurate output voltage with low dropout voltage and low quiescent current.
