Let's hope we can't always count on you in future for top-posted
dumb replies too! The excellent Holtek HT71xx series, which only
draws 4uA, while delivering 30mA, was suggested by Mike Harrison,
not John Fields. :>)
They also have the HT71xx-1 series, trimmed to 3%. And the
HT75xx-1 series, drawing 3.5uA, delivering 100mA, trimmed to 3%.
And coming next year the HT73xx series, drawing 3uA, delivering
300mA, and trimmed to 2%. Very impressive!
> Who distributes Holtek stuff anymore?
Holtek is an excellent source for low-power components, e.g. their
400nA 2V timer IC, etc. They are and continue to be profitable and
are growing nicely, even in this slump, which is important. You buy
from the factory or one of their offices. The North American sales
office is Holmate Semiconductor, Inc., 48531 Warm Springs Boulevard,
Suite 413, Fremont, CA 94539. Tel: 510-252-9880 Fax: 510-252-9885
All this info obtained from the web, as John suggested.
I have used Holtek for many years in the past for production designs,
and have always been very happy with them and their products.
