Lm You have three choices to get a higher current than 1A. What is your input voltage? Usually, the biggest contributor of heat to a linear regulator besides the current draw is the supply voltage. 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.

The chances dtasheet that your LM is fine but you haven’t got it on a decent heat sink. By continuing to use this site, you are consenting to our use of cookies. All of them require a heat sink!


2pc Voltage Regulator IC LM7805K TO-3 Vo= 5V 1.5A Pd=15W Wing Sing ( 7805K 7805

How datashheet calculate the combine shipping? For a better experience, please enable JavaScript in your browser before proceeding. Sorry, I meant linear regulator. 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.

What about using an LM which can handle 1. If you buy some item, and order 4 lots.

Hope you can understand. Like us on Facebook. Hi Watzmann, Here’s one, but you’re gonna need a large heatsink because it will run as hot as the previous one. Lm78S05 and you’re going to need a heatsink. You must log in or register to reply here.

Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at 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.


Thanks for you looking. Possibly the TSX series, don’t know whether lm7850k go up to 5V though. 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.


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. If you need the fastest delivery, take EMS please, but more expensive.

Plus other items their additional lot shipping price. It’s a switching regulator, therefore it will require a large heatshink. Hong KongCustom Bundle: Articles Top Articles Search resources.

If you need insurance, email me before paying, please. Wing SingNon-Domestic Product: Hi Alli’m running a stepper motor with a supply from LMmy problem is the stepper draws more than 1. Forums New posts Search forums. LMKModified Item: Does the regulator have alarge heat sink? Hero Banned Mar 7, Media New media New comments Search media. Each bidding lot is for 2 pcs Net weight approx: If your input-output voltage is too large then it will heat up a lot more quickly. The chances are it’ll stand up to 1.
