Lm 7805 !!!

If you feed a from an 8v datasheer, you’ll drop 3v across the part and at 1a of current, that’s 3 watts of dissipation, easily handled. Started by fastline Yesterday at 8: You must log in or register to reply here. Just saying hello Started by MichaelaJoy Yesterday at 6: Potentiometer Questions Started by norbss Yesterday at All of them require a heat sink!

On the other hand, if you’re supplying it from a 20v supply, that’s a 17 volt drop across the regulator datqsheet at 1a, 17 watts of power dissipated. Does the regulator have alarge heat sink?

It’s a switching regulator, therefore it will require a large heatshink. Lm You have three choices to get a higher current than 1A. Besides that, a usually reacts “negatively” to overcurrent spikes like that and tries to shut down unless you’ve hung a ridiculously-large amount datasjeet capacitance on its output.

Hope you can understand. Each bidding lot is for 2 pcs Net weight approx: Lm78S05 and you’re going to need a heatsink. 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. Lm7850k, I meant linear regulator. To participate you need to register.



Possibly the TSX series, don’t know whether they go up to 5V though. Forums New posts Search forums.

If your input-output voltage is too large then it will heat up a lot more quickly. Thread starter watzmann Start date Mar 7, Hong KongCustom Bundle: Great seller with very good positive feedback and over 50 ratings.

If you buy some item, and order 4 lots.

The chances are that your LM is fine but you haven’t got it on a decent heat sink. What is your input voltage? Why are you regulating stepper motors anyway? Click here to register now. Articles Top Articles Search resources. Hi Watzmann, Here’s one, but you’re gonna need dqtasheet large heatsink because it will run as hot as the previous one.

See Details on eBay Watch Contact. Hi Alli’m running a stepper motor with a supply from LMmy problem is the stepper draws more than 1. Even the LM will shut down quickly if you try powering something that takes a couple of amps datazheet 5v if you’re using a 30v input. If you need the fastest delivery, take EMS please, but more expensive.

LMKModified Item: If you need insurance, email me before paying, please. Usually, the biggest contributor of heat to a linear regulator besides the current draw is the supply voltage. Wing SingNon-Domestic Product:
