Powering a Raspberry Pi from 12 V DC

I new to electronic engineering and am trying to learn electronic engineering by creating little projects. I have a few questions about powering my Raspberry Pi (5 V DC @1000 mA) from a 12 V DC 1000 mA power supply. The 12 V power supply will provide power to the TFT monitor, and I want to also power my Raspberry Pi from the same source.

Powering a Raspberry Pi from 12 V DCAfter doing some research, I can make a 5 V regulator using a 7805 voltage regulator and two 100 µf electrolytic capacitors. The plan is to put a heat sink on the 7805 to help dissipate the heat. My goal is to have one source of power input for my project.

  1. Is this the correct approach?
  2. Is my schematic correct?
  3. Is my hookup correct?
