MC78L08ACDG Application Field and Working Principle

Introduction

MC78L08ACDG is an 8 pin Three-Terminal Positive Voltage Regulator which has been developed by ON Semiconductor Company. It is a high-performance linear voltage regulator with many features and benefits. It is available in TO-92, SOT-223, SOT-89-3, and D²Pak packages, making it well suited for any imaginable application. It is an ideal choice for use as a low cost, low power and low drop out voltage regulator.

Application Field

MC78L08ACDG is highly recommended for applications such as automotive, consumer, battery powered systems, general-purpose and low power linear voltage regulators. It is capable of supplying 0.1mA to 1A power outputs of adjustable voltage. The regulator provides excellent line regulation in the 5V range. It is also designed to exceed the requirements of the following specifications: JEDEC-C and European Standard EN60950.The highly efficient MC78L08ACDG can be used to regulate positive regulated voltages of up to 8 V, making it the perfect solution for a variety of applications. The low noise enables the use in noise sensitive applications and the extremely low current consumption increases the battery lifetime in portable applications. MC78L08ACDG is one of the most efficient regulators for its size, having a power dissipation as low as 225mW. Its minimum on-state resistance is also quite low for its size, making it ideal for use in low current applications such as powering small sensors and ICs. Its high-frequency operation allows it to be employed in higher frequency applications, thereby reducing the overall size of the device, making it the ideal regulator for applications requiring low power consumption, low noise and small size.

Working Principle

The MC78L08ACDG is a three-terminal positive voltage regulator with a high input voltage and low output voltage of up to 8 volts. The regulator is designed to provide a constant output voltage despite fluctuations in load, temperature, and line voltage. The working principle of the regulator involves a comparison between the voltage applied across its input and output terminals. If the difference between the input and output voltages exceeds the reference voltage, it turns on the pass transistor to reduce the voltage difference, which in turn maintains a constant output voltage. It also features short circuit and over temperature protections that are provided by a thermal shutdown circuit that triggers when its temperature exceeds a preset level. The reference voltage of the MC78L08ACDG varies depending on the temperature, allowing it to maintain a constant output voltage even when the temperature changes. The internal circuits of the regulator are also highly efficient and have low power dissipation, making it ideal for use in battery operated applications.

Conclusion

The MC78L08ACDG is an 8-pin three-terminal positive voltage regulator that is highly recommended for use in applications requiring low power consumption, high accuracy, and low noise. It is capable of supplying power outputs of adjustable voltage ranging from 0.1 mA to 1A. The highly efficient regulator has a low noise level making it suitable for use in noise sensitive applications and features excellent line regulation in the 5V range. The MC78L08ACDG has a wide range of applications and is capable of providing a constant output voltage despite the changes in load, temperature, and line voltage.
