 Bigger Bigger  Smaller Smaller  Reset Reset

First of all, sorry about my english.
I'm working on a project that will work a long time without stop ( days if possible). I'm looking for use a car battery 12V 9Ah. It's possible to reduce the voltage to 3.3V with an I.C. and put it on the supply voltage (jack)?

Thank you all very much

If you looking for an IC, which lowers 12V to 3.3V, these can help. 919-R-783.3-1.0 This is a Mouser part number but there many others and from other vendors too.

You can't put 3V3 on the power jack it is too low.
The range is 7 to 12V so you could connect your battery directly to the power jack.
