Hi,

Can some one help me to chose a LOW Noise Linear Regulators (LDO)

I am checking this : http://www.linear.com/pc/viewCategory.j … 1003,C1040

looks promising!

really i need your advice guys

Thanks

What noise level do you need? Most LDOs are pretty good.

well, i don’t really know the level of noise. i will use it with some Gyros and Accelerometers and i want to get a noiseless voltage to those sensors as low as possible

There will be much higher noise sources on your board, like the MCU and its clock, than the LDO. It isn’t relevant.

according to your experiense …can you tell me a good one?.

what about the Linear’s serie??

I usually use the ST LExxCZ parts and the LM1117.
