MC7808BDTRKG Application Field and Working Principle

MC7808BDTRKG, also known as Texas Instruments Voltage Regulator, is a linear voltage regulator, meaning it regulates voltage while consuming the exact same amount of current that a powered circuit needs. This voltage regulator is mostly used in automatic equipment, electric tools, medical equipment, and electric toys.

The most common use for this voltage regulator is for providing DC voltage for electronic circuits, such as those in digital cameras, camcorders, computers, and other electronic devices. The MC7808BDTRKG can provide a constant voltage that is within a range of 1.5 volts to 25 volts, with a selectable output current from 1.5mA to 10A. It is ideal for adjustable supply applications due to its wide range of operations.

This device consists mainly of two NPN transistors and a Zener diode connected in parallel with the transistors in order to form a voltage regulator circuit. The two transistors act in the current regulator and form a differential amplifier. The Zener diode provides voltage regulation. By adjusting the Zener diode’s voltage, the voltage output of the voltage regulator can be adjusted.

The MC7808BDTRKG has a wide operating temperature range of -40°C to +125°C, making it suitable for a variety of applications. It also has low noise levels, making it a good choice for audio applications as well as those requiring low levels of EMI. Additionally, it has very low power consumption and excellent transient response characteristics.

In general, the MC7808BDTRKG voltage regulator circuit is very simple and efficient, making it an ideal choice for many electronic circuits. Its wide temperature range and low noise levels make it an attractive option for applications that require smooth and reliable operation. Moreover, the adjustable output capability gives it an edge over other voltage regulators when it comes to adaptability for different applications.
