Standalone Arduino - power supply question

Hi, I am building a 'standalone' project using a Atmega 328P-PU chip, and using a LT7805 regulator, but am not sure what value capacitors to use on the input and output sides of the regulator.
I have looked at the LT7805 spec sheets and they use 0.33uF on the input and 0.1uF on the reg output, which seem extremely low values????

I use 10uf and a 0.1uf on the input and 22uf on the output ... But it really depends on what you'll be drawing from it... for the arduino they have a different viewhttps://arduino.cc/en/uploads/Main/arduino-uno-schematic.pdf

It was the arduino schematic that confused me, as the 2 X 47uF caps are a lot different in value to the 0.33uF & 0.1uF as proposed in the LT7805 data sheet...

Yes! but there are two convertors and it designed to allow quite a few mA through
