Hi List,

I'm looking for a 5V out switching regulator with a quiescent current of <1=
=20
mA, capable of supplying 300 mA. It should operate across a wide voltage=20
range, from 8V up to 32V, and be able to survive 36V. It must also be small=
,=20
and cheap.

We did our prototyping with Seiko's S-8520:

It's a nice little device, but it has two big flaws: it can only go up to=20
16V, and it has a three month lead time.

I understand some of you chuckled in disbelief, or even rolled on the floor=
=20
laughing after reading the first paragraph (you know who you are), so let m=
e=20
relax the requirements a little bit:

I would be OK if I could find a regulator that accepts 8-18V on the input,=
=20
and survives 24V for 10 minutes, as long as it meets the quiescent current=
=20
spec. I'm even OK with adding cheap external components to shut off the=20
regulator if the voltage exceeds 16V.

Thank you in advance for your help.
