You're right, it's not from Guido - - it's a 10ppm NDK jobbie in a small case, if I recall, but I forget which DIY boutique I got it from.

Though Mr. Tent's canned oscillators might be a better way to taste-test this regulator... and I wouldn't mind playing one of them off against these discrete circuits.

My package showed up yesterday, thanks Jocko .

I ordered the mouser transistor, and have the resistors and leds, just need to buy a few panny caps and I can put it together.

Amazing that the PO can actually deliver stuff in a reasonable manner when they feel like it.

IOW, I still don't send stuff to Chicago, because they somehow never feel like it there.

Jocko

Mines arrived yesterday already

I've just arrived home from holidays and the good stuff was in my mailbox.
Looks like the mail from Texas lands here quite fast.

Pedro, I'll send you the two PCBs next monday or tuesday.

Ok, I'll wait until next week...
Portuguese PO service has been kind of 'delayed'... inside our Country... Blue Mail usually arrives in 3 days... it's supposed to be 'next day'...

Got ours Friday morning. The mystery op-amp was a surprise...

For testing purposes I'm planning to install one PS in my upgraded Marantz CD6000(OSE)...

Jocko,

Pedro has already received his PCBs.
You forgot to send him the schematic.
I could forward him the schematic, as he is your... huh... client.
But I need permission from the manufacturer.

Old people.............what are you going to do with us?

Go ahead and send it to him. Even though that file size is only 10 kB, it takes quite a while to send on my crappy dial-up. I have no idea why.

As for your other issues.............

Uh, I did not intend for one regulator to power the whole works. The uP does not need power that quiet. You can either:

Power it off of something else, or better yet,

Power it off of another "misery" regulator. I tried to make them as inexpensive as possible, just for that reason. (You will notice that it has the same pin-out as a crappy '78xx regulator. For a reason.) Of course, since it doesn't really care about 1/f, you leave the RC filter off of it.

See how easy that is?

NO? Well, I tried.

Jocko

Probably because what you sent me was a .bmp file with some 300Kb.



Jocko, you say that because you don't know that beast.
Space is really tight inside, 4-layer PCB, no clearance under it (~2mm between PCB and chassis bottom).
It is such a small fit that your PCB did only fit in the horizontal position, and barely so. (!) The lid wouldn't close.
You see, it is easy for me to cut a PCB trace and insert a 78LXX reg for the uP. The problem is that sometimes that power trace is burried deep inside the 4-layer PCB, which only leaves me the option of giving it with the hammer.
PS: I didn't want to remove the 1/f filter because other than the uP (which is not important at all) there are other chips that would benefit from it.

More precisely, it was a .jpg with 156Kb size.
Converted to .gif in Irfanview, it gets down to 37Kb, without any loss of quality.
More apropriate to send through a "thin" line.

I don't know how the hell you got a .jpg, because that was done as a bitmap, and converted to .gif. Converting them to .jpg from bitmap looks like doo-doo. So I never do it that way. Smaller, but they look horrible.

I wonder if there is some conversion process involved in how I insert images into mail. I simply do not have a .jpg of that drawing. Go figure. Guess from now on that I will make it an attachment. Doubt that Bill Gates will find a way to muck that up.

Jocko

Jocko, your schematic came in the body of the e-mail, instead of being an attachment.
Somewhere it was converted to display on screen.
I don't know if it was my Opera browser/e-mail client. But I do receive attachments without problem.
Anyway, you use HTML mail, which is somewhat "heavy" for dialup. It looks nicer, though.

Mine came as a .bmp, exactly 1MB in size when I saved it... embedded in the email, very nice looking.

I'm just putting my reg together now, trying to fit a 1.5mA CRD - - in a tiny SMD package - - onto the CCS spot. The whole thing arrived before Labour Day, so USPS must have improved since I lived over there. Groovy op amp!

OK, now I am really confused. Maybe I inserted the wrong image.
