Works great for pinballs Review by Pierre
Installed several of these on pinball machines, especially on WPC89 power driver boards. Works exactly as expected, with a word of warning though : it's necessary to use metal screws and nuts to maintain continuity between component and solder side. The first time I installed one of these, it didn't work at all, because the small washer under the factory nut was shorting with a small SMD resistor - at least short circuit protection works. So I reajusted the nut and it worked absolutely fine.

For my second try, I decided to use plastic nuts to avoid shorting the resistor. I only had 1,40 V on the +5V test point. I took the board apart only to realise continuity was missing for the "casing" of the regulator.

So : for pinball machines, use the factory METAL screws + washer AND make sure the nut isn't shorting the SMD resistor the closest to the mounting hole. (Posted on 4/5/18)
Great Product Review by Pintech
I've used over a Dozen of these now with NO problems. Adjustable voltage is a plus and it runs very cool. (Posted on 3/28/17)
Wow!! Review by Alain
Finally solved my reset problem on the Williams pinball have been working on. I changed 4 times the LM323K with new ones, with the exact same result, the voltage kept falling down to 4.78v after a few minutes. I install the PSU5 and wow! what a change. The voltage never drop below 5.00v.
For now on I only buy the PSU5 instead of the original LM323K and will tell all my friends about your products.

Thank you (Posted on 6/9/16)
Where's the Beef? Review by Ralph
I can't find a data sheet to provide full info on using this module. At least it would be useful to provide a part number for the chip used. I can see the board is bigger than the TO-3 package it replaces. I would need to have full mechanical details before I could use this device.

I give this device a C- until they provide a data sheet. (Posted on 10/3/15)
Lovely device! Review by th_in_gs
I bought one of these not to replace a LM323K, but to use in a new project.

I couldn't be happier. It's very easy to interface with, and runs very cool, even with a 2A draw. It's small, and looks very neat too, which I always like.

Would definitely recommend. (Posted on 8/1/14)
