The chances are that your LM is fine but you haven’t got it on a decent heat sink.

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. Replacing a 4 pin leaded inductor with datqsheet 2 pin Started by gkmaia Yesterday at The chances are it’ll stand up to 1. Usually, the biggest contributor of heat to a linear regulator besides the current draw is the supply voltage.


Why are you regulating stepper motors anyway? Lm You have three choices to get a higher current than 1A.

See Details on eBay Watch Contact. Great seller with very good positive feedback and over 50 ratings. Hero Banned Mar 7, Welcome to our site! On the other 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.

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. 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. How do calculate the combine shipping? Hi Watzmann, Here’s one, but you’re gonna need a large heatsink lm78055k it will run as hot as the previous one.
