IC 7805- The input voltage must always be higher than the output voltage by some minimum amount (typically 1.5 to 2 volts) . 7805 is a linear voltage regulator‚ so it is not very efficient and it has drop out voltage problem. As they are based on a linear regulator design‚ the input current required is always the same as the output current. As the input voltage must always be higher than the output voltage‚ this means that the total power (voltage multiplied by current) going into the 78xx will be
