You can use:

You can but the regulation  is not very good and I would at least include some capacitors.


The way you have it in your schematic isn't the same as how you have it wired up!


What's the best/cheapest regulator i can use to go from 5v to 3.3v or approximately ?

I am 100% sure that they are not the best, but the 1117s are the cheapest and crappiest regulator that gets the job done.


If you actually look at the datasheet for a 1N400x diode, you'll see it's forward
drop varies from about 0.6V @ 50mA to about 0.8V at 250mA, so the output
of the 3 diode ckt will vary from about 3.2V to 2.6V with those loads. I'd go
with an LM1117, or other v.reg as mentioned, instead.
