magic's point was about not necessarily requiring an LDO, and I gave complementary info afterwards.
Anyway, even if not strictly requiring a low dropout, that wouldn't help much as the offering is very limited: 29x12 are not a match as I explained above, and the LM337, beside its highish dropout voltage, is unobtainium in SMD packages at the moment (or the larger DPACK stuff). So that's pretty much it.
Good matches have been mentioned: TPS7A3001, LT3032 (I could use the positive regulator in it to replace one other regulator in my design), but they are either unobtainium or pretty expensive. Now given the LT3032 would be two regulators, its price is not that awful though, so that might be my pick. Still a bit pricy. The LT1964 could also be a match, but it's expensive and its PSRR is not that great. Now I could add some pre-filtering to improve the PSRR if I find a good match otherwise, as there aren't many at all anyway.
There are tons of matches for positive LDOs with similar characteristics (and even more with lower positive input voltage, in terms of PSRR and low noise), but extremely few for negative LDOs. I guess there is little market. And the current state of shortage doesn't help.
