xenobie Posted February 25, 2019 Report 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
HarryA Posted February 26, 2019 Report 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
