Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at Just saying hello Started by MichaelaJoy Yesterday at 6: The chances are it’ll stand up to 1. 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.

Each bidding lot is for 2 pcs Net weight approx: Lm78S05 and you’re going to need a heatsink. What about using an LM which can handle 1.

What is your input voltage? To participate you need to register.

Wing SingNon-Domestic Product: Thanks for you looking. 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 dataeheet you’re using a 30v input.

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

If you need the fastest delivery, take EMS please, but more expensive. Anyway, the Import duties, taxes and charges are not included datashwet the item price or shipping charges. It’s a switching regulator, dtasheet it will require a large heatshink. 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. Welcome to our site! If you buy some item, and order 4 lots.

Usually, the biggest contributor of heat to a linear regulator besides the current draw is the supply voltage.
