Well, maybe a tad unfair but ...
The KA7605Z regulators that I reported as a great "find" the other day turn
out to be only ho-hum.
This may be RS's fault as they provided the specs.

These do not CLAIM to be low quiescent and indeed they are not - typically
2.5 to 5mA at no load.
That's bearable if they meet the low dropout claim - especially the 0.03
volt that RS claim for them.

At no load they dropout at around 1.4v differential and this rises to about
1.6V at about 20 mA.
Best case this is over 40 times worse than RS's claim.
Hmm - maybe the NZ consumer guarantees act may be useful for once ...  :-)

All this at "room temperature".

Definitely not a low dropout part by any definition. About the same as a
standard 78L05.
Ah well.
