Hi Jim, Yes, please reply if/when you try it with results. Thanks for offering to send me one but yeah, they’re pretty cheap. I order parts regularly and can just add one to my next batch. Thanks! Zack ---

Hey Zack, Just wanted to let you know that the QS8J4 did the trick. It has the same J04 marking code. I just soldered mine in and it works like new. Sometimes I scare myself… ---

That’s great, thanks! I’ll see if that does it on my end, too. ---

One final update from me: My DD-500 works, too. In installed this IC, and that’s all it took. Thanks again, Jim! [Previous page](https://forum.digikey.com/t/voltage-regulator-id/6869.md?page=1)
