Hi,

Here is a link to a short list of regulators that emulate the 78xx series regulators with an actual switching regulator so it's not linear so it is much more efficient in many applications.

Note these are SWITCHING regulators not the usual 78xx linear type but can be used in place of a linear one for better operation in many cases.

Cool! Are those new? I haven't seen them before. Maybe this will finally end the ubiquity of the analog parts.

Be prepared for sticker shock. They're convenient, drop-in replacements and you pay for it.

Hi,

I have heard of these before but this set looks smaller so i dont know how long they have been around.

As you can also see from the other reply here, the cost is not cheap. I am seeing 5 dollars to 10 dollars (USD) depending on current rating i think. But if you really need a switcher for the efficiency, that's the best bet i think because you dont have to do any work, just pop one in.

There have been 3-terminal switchers to replace the 7800 series on the market for probably 20 years, at least.

8~36V 5V@1A for $3.3 That is double what I pay for the 5 pin ( that also doesn't need a heat sink )... But these prices are for 1 off's maybe it'll be cheaper for 25!! Good spot though! Cheers for that MrAl! #### dendad Joined Feb 20, 2016 3,781 I have been using them for years now. In fact, there is only a couple of products I have that uses a linear reg. The first was a Power Trends 78HT205HC that was about an inch square. And in 1994 they were a lot of money. But the savings in power supply size and heat is really worth it. Now I use Recom and Tracpower parts. These are a lot smaller than the original one used. If you have not tried them, have a look. It is well worth while ,even if you follow with an LDO linear reg.

Hi there Ian,

Yeah a little pricey there, but i guess if you really need a switcher it is easier and cheaper than designing one with a chip and inductor and diode and two caps, etc. The higher current models are more expensive too.

I think i got the notification in the email about these parts. Once in a while i get some good ideas that way. "They" know i look for parts online

Thanks for sharing that MrAl. Pretty neat little regulators.
