Working Principle

The KA7806AE circuit consists of an internal voltage reference and an adjustable error amplifier. The adjustable error amplifier compares the output voltage to the reference voltage, and has an output current proportional to the difference between the two. This output current is used to adjust the output voltage of the regulator to the desired level.

The output voltage of the KA7806AE is controlled by the output of the adjustable error amplifier. It is adjusted with an external feedback voltage divider. The output voltage can be adjusted by changing the resistance of the divider. The output voltage can be monitored using the voltage monitor pin.

The KA7806AE has an adjustable current limit circuit which limits the output current of the device. The current limit can be adjusted with an external resistor connected to the current limit pin. An over-temperature protection circuit is also included for improved reliability.
