Looking at 78xx circuits, just wanted to confirm if my power source is 12v switchmode regulated PSU rated output of 14.2A(old 360 PSU) and I want to use LM7805 (have many on hand) to get 5V , do I really need caps for filtering? can I just attach to heat sink and paralle them up for 5V@3+Amps or is there suggestion/need for some current protection, or a suggestion for better way to step down the voltage. My application is for powering a couple of USB hubs and Raspberry PI(5V needed) along side a USB2HDD adaptor([email protected] needed)
Thank you for reading and any and all advice is very much appreciated!
