MC79M05BDTRK Application Field and Working Principle

The MC79M05BDTRK is a low-dropout, 3-terminal voltage regulator that uses an N-channel pass element for current regulation. This device is suitable for applications where lower voltage levels are needed, and also for automotive applications. It is also suitable for applications where high-current, wide efficiency range, and low-dropout voltage performance are required. Additionally, the MC79M05BDTRK can be used as an adjustable voltage regulator in several different applications.

The MC79M05BDTRK can provide high current output up to 3 amps, adjustable voltage range of 1.2V to 11.5V, and high efficiency due to its low quiescent current design. It also features low temperature coefficient and better long-term stability. Furthermore, it has short circuit protection and over-temperature protection as built-in features.

Working Principle

The MC79M05BDTRK is a 3-terminal positive voltage regulator with the N-channel pass device for current regulation. It works by creating an electrical potential between the input and output terminals by using the N-channel pass device to actively regulate the current from the input to the output. This pass device is connected to an internal voltage reference and the output voltage adjusts according to the voltage reference set at the input. An internal resistor divider is also used to establish the output voltage and is adjusted by the same voltage reference. When the output voltage is greater than the voltage reference, the pass device turns on, creating a current path from input to output and allowing current to flow. When the output voltage is lower than the voltage reference, the pass device turns off and blocks current from flowing, hence regulating the output voltage.

Applications

The MC79M05BDTRK is a versatile, adjustable voltage regulator that is suitable for a variety of applications. These applications include automotive battery, automotive power supply and voltage conversion, microprocessor power supply, industrial power, and portable power. It is also suitable for use in applications where a fixed voltage output is required, such as an adjustable switching power supply or an adjustable linear power supply. Finally, this voltage regulator is also suitable for use in analog and digital circuits.

Conclusion

The MC79M05BDTRK is a low-dropout, 3-terminal voltage regulator that uses an N-channel pass element for current regulation. It is suitable for automotive applications, microprocessor power supplies, industrial power, and various other applications. Additionally, its adjustable voltage range, low temperature coefficient and short-circuit protection make it ideal for a variety of applications.
