LT1010 rail splitter not splitting

I looked at the numbers and even the TLE2426 would have been shoehorned into the existing board. The present circuit is a zener and resistor (both 0603 I believe) without a cap because there is no room. The TLE2426 could actually be a 3 pin part so maybe a plain jane SOT-23 would be better or preferably a SC-70. Jeeze, sometimes I have nightmares about having to rework that board. It was like a jigsaw puzzle with *extra* pieces and I had to make them all fit!

Adding an SO16 would mean I'd have to replace the FPGA!

I did a bit of a search and I don't see where anyone else makes such a part. Interesting. I guess it was a niche that just one maker could fill well enough.

I think that's right. It's really a convenience part more than anything. (And of course the TCA0372 runs warm to the touch just from its quiescent current.)

Nobody said the part was an unqualified ridiculous, the original statement was that as a standalone part it's ridiculous.

I wasn't aware that it may be a mooo'ving target.

When the nurse finished giving me a hearing test a couple of weeks ago, she made a comment that I did not understand. I said What? and she looked at me in disgust. I suddenly realized what she was thinking.

I understood, but didn't entirely agree. One wouldn't design a product that way, for sure, but from the OP's choice of parts, I expect this is a one-off and they're what he has in his drawer. For that sort of thing I wouldn't hesitate to use it myself--the LT1010 would work fine for many applications.

I still use a bunch of LF356es in one-offs, because they work fine and I have a couple of hundred of them.

Well, he and I do a lot of physicsy stuff, so it's important to choose the right sleazy approximations.

Your new diet is threatening the calibration of the LPMU.

My local gravity decreased by about 12% to date. Gravitas is still mostly absent, and my Bubba impression has gone all to hell. ;)

I call it the P. G. Wodehouse diet--laying off the starchy foods.

Fabulous stuff. Nobody could write like Wodehouse.

Another good diet book is "Something New"
