xenobie Posted February 25, 2019 Report Share Posted February 25, 2019 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: 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? 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? Quote Link to comment Share on other sites More sharing options...
HarryA Posted February 26, 2019 Report Share Posted February 26, 2019 If you do not need SMD perhaps "The LT138A/LT338A (LM138/LM338) series of adjustable regulators provide 5A output current over an output voltage range of 1.2V to 32V." The LM338 is about 1$ each on ebay. gztoppower 1 Quote Link to comment Share on other sites More sharing options...
