Thank you. I know what I'm looking for, and how it is called. I just
wanted to know if someone is already using a suitable part that can
recommend to me, especially one that can be easily obtained through
distributors like Farnell, DigiKey, Amidata...

Ideally, it should be one with a PMOS pass transistor and a very low
quiescent current (100 uA max). So far, not much luck with Farnell.


lp2951 or lp2950 from national should fit the bill, dil and soic
versions available from farnell

Thanks again to both of you. The ground pin current (approx 3 mA @ 60
mA) kills me. That's due to the PNP. I have to connect around 200
units in parallel, hanging on a 24 V bus, and I'm trying to minimize
the losses. I must say, I'm quite amazed that I cannot find one with a
PMOS pass transistor that works at these voltage levels.

Best,
