How much voltage does a Raspberry Pi need?

According to Raspberry Pi forums, you can supply 5V with a ±5% uncertainty, meaning you could supply from 4.75 to 5.25 volts. The 7805 voltage regulator should be okay for your project, for it could supply a max of 1A and it stays within that uncertainty.

What kind of power supply does the Raspberry Pi need?

The Raspberry Pi 3 is powered by a +5.1V micro USB supply. Exactly how much current (mA) the Raspberry Pi requires is dependent on what you connect to it. We have found that purchasing a 2.5A power supply from a reputable retailer will provide you with ample power to run your Raspberry Pi.
