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.

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.
