Hi there! I'm creating my first standalone project that has to be mounted in my motorcycle. The power supply will be a 12V battery (5Ah 30A), so I need to convert from 12 to 5V. I bought an LM2596, but since I'm a complete ignorant, does it need the help of an L7805 or it does all the job alone? …

Is L7805 still needed when using an LM2596?
