Working Principle
The MC7808BTG works on the principle of voltage regulation. It has two voltage inputs, one being the input voltage and the other being the reference voltage. The input voltage is compared to the reference voltage and the output is regulated depending upon the difference in the two voltages. The output voltage is then regulated by a voltage regulator and a voltage divider network to maintain the desired output voltage.
The MC7808BTG also has a current-limiting feature, which prevents the output voltage from exceeding the upper limit of the output voltage. The current-limiting feature prevents the device from being damaged due to excessive current. The MC7808BTG also has an over-temperature protection feature, which prevents the device from being damaged due to excessive temperature.
In addition to these features, the MC7808BTG has a built-in thermal shutdown circuit, which protects the device from over-voltage and over-temperature conditions. It also has a wide range of input voltage and adjustable output voltage.
