Power supply circuit ideas

Recommended Posts

I have a project which required 3.3v (170mA), 5v (1.2A), 12V (not sure yet). For the 3.3v I am going to use an AMS1117-3.3 which is more then enough so this is not an issue.

I have 2 questions mainly as follows:

  1. I want to use 8x of these stepper motors driven by 8x DRV8825 and I am not sure if the specifications are correct but could it be 50mA each totaling 400mA @ 12v?
  2. I have a couple of AMS1117-5 as well and since they are a max of 1A, can I chain these? if not what do you recommend?
