With the circuit presented here, this current is increased by adding a power transistor (t3 in the circuit diagram below) on a heat sink. The simulation is carried out using matlab software. The transistor tip2955 acts as a switch here and since we need the lm7805 to act as a fixed 5v supply we will attach the adj pin of lm7805 to the ground.
