I want to power both an Arduino and a split supply OpAmp cct from a single switch mode 15V o/p wall wart psu.
That wouldn't work
. Notionally I always though of linear regs as little more than this kind of zener arrangement and it would reduce my component count.
the cheap and minimal-external-component voltage inverter chips are all smd!
