Why are you regulating stepper motors anyway?

Even the LM will shut down quickly if you try powering something that takes a couple of amps at 5v if you’re using a 30v input. Hi Alli’m running a stepper motor with a supply from LMmy problem is the stepper draws more than 1. Thread starter watzmann Start date Mar 7, On the dxtasheet hand, if you’re supplying it from a 20v supply, that’s a 17 volt drop across the regulator and at 1a, 17 watts of power dissipated.

The chances are that your LM is fine but you haven’t got it on a decent heat sink. If you feed a from an 8v supply, you’ll drop 3v across the part and l7805k 1a of current, that’s 3 watts of dissipation, easily handled. The chances are it’ll stand up to 1. If you need the fastest delivery, take EMS please, but more expensive.


It’s a switching regulator, therefore it will require a large heatshink. If you have problem, email me before shipping please, I will change to regular airmail without registered, but the lost package risk is so high, and I can not response for it.

You can calculate by yourself or ask me a combine shipping cost quotation before bidding, or directing order and wait a moment, I will sent a new and correct invoice to you. Great seller with very good positive feedback and over 50 ratings. Possibly the TSX series, don’t know whether they go up to 5V though.
