In this post, the below designed circuit gives a stable 5V DC output with high current up to 4A which uses the 7805 voltage regulator IC and multiple TIP41C transistors connected in parallel, because the normal 7805 IC alone gives around 1A current and we add external power transistors to increase the output current. Moreover, […]
