Hey folks...

What should I use to protect my electronic module (LDO 3.3V regulator, uC, RF transceiver) on automotive enviroment... This module will consume about 50 mA.

I found this on ST site... is it good enough or should I add something else, like inductor, PI filter, and so on...


Any suggestion are welcome

Thanks
Rafael
 

you need to drive your cricuit using car battery , what is your problem.
is there any prob of voltage ?
 

yes manish12, I´ll power my circuit using car battery...

And I know that I must have transient protection, for example, spikes on the 12 V line when you start the car.
