Working Principle of MAX663EPA

The working principle of MAX663EPA is based on the linear regulator architecture. This voltage regulator has an error amplifier which compares the voltage present at the output with the reference voltage. This shows that the output voltage of the regulator is made to follow the reference voltage. The input power is supplied to the regulator which as, then regulated by the regulator itself to a specific voltage. The output of regulated voltage is then monitored using a current feedback loop. This loop is used to track any change in the output voltage and to minimize the possibility of any overvoltage. In this case, the pass element is a p-channel MOSFET, hence the input current is less than the output current.
