[sdiy] Negative LDO Regultors - where are they all?!

[Tom Bugs]

Hi,

Wondering if people can suggest to me *ANY* sources of low dropout 
negative regulators - pref. with specs: adjustable Vout (must do -15V) 
and current 500-1500mA (or more even)

I've been finding it really hard to track down something suitable.. 
Loads of positive LDO regs, but negative ones are really thin on the 
ground.

Pretty much the only one I've come across that looks ok is the LT3015 - 
but that is currently not stocked by many regular distributors.
The LM2990 looks as thought it may be of use - but I'm distinctly put 
off by the description 'Designed for vehicular applications'

Thanks in advance for any pointers.

Tom
