Hi Alli’m running a stepper motor with a supply from LMmy problem is the stepper draws more than 1. Hi Watzmann, Here’s one, but you’re gonna need a large heatsink because it daatasheet run as hot as the previous one. Besides that, a usually reacts “negatively” to overcurrent spikes like that and tries to shut down unless you’ve hung a ridiculously-large amount of capacitance on its output.

Each bidding lot is for 2 pcs Net weight approx: Super high amount of views. Taipei county, TaiwanShips to: I am notifying you, because this is a registered package, so, please arrange to have someone at home to sign for the datasneet. What is your input voltage?

You must log in or register to reply here. Why are you regulating stepper motors anyway? If your input-output voltage is too large then it will heat up a lot more quickly. Lm78S05 and you’re going to need a heatsink. What about using an LM datasjeet can handle 1.


The chances are that your LM is fine but you haven’t got it on a decent heat sink. Like us on Facebook. Thanks for you looking. By continuing to use datashee site, you are consenting to our use of cookies.

Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at It’s a switching regulator, therefore it will require a large heatshink.

Lm 7805 !!!

Hope you can understand. If you need the fastest delivery, take EMS please, but more expensive. Sorry, I meant linear regulator.

Usually, the biggest contributor of heat to a linear regulator besides the current draw is lm7805, supply voltage. Boncuk New Member Mar 7, 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.

All of them require a heat sink! Wing SingNon-Domestic Product: On the other hand, if you’re supplying it from daatsheet 20v supply, that’s a 17 volt drop across the regulator and at 1a, 17 watts of power dissipated. Possibly the TSX series, don’t know whether they go up to 5V though.

If you feed a from an 8v supply, you’ll drop 3v across the part and at 1a of current, that’s 3 watts of dissipation, easily handled. See Details on eBay Watch Contact.

Does the regulator have alarge heat sink? Lm You have three choices to get a higher current than 1A. The chances are it’ll stand up to 1.
