cheap hams, I would recommend the Vinifinity from CUI. V7805-500 (0.5
amp) should work and it is $8.
Or the V7805-1000 (1 amp) if you want more headroom:
I've used hundreds of these parts and they work pretty well. PowerTrends
used to make a similar part. TI bought them and still sells a few variants.

doesn't draw any more than that.
