Other Parts Discussed in Thread: TPS7B7702-Q1

Hi, Team

A Car-OEM customer GAC plan to use TPS7B7702-Q1 in their T-Box product. One output channel of TPS7B7702-Q1 is used to power GPS antenna, the other channel is used to power the microphone. Customer worry about the noise form antenna will interfere the microphone.

They want to know the noise crosstalk performance between 2 channels of TPS7B7702-Q1. Could you help to provide it?

Thanks

Hi Kevin,

For our deal channel antenna LDO TPS7B7702-Q1, there is no problem to use as this kind of topology. this device has been used like this in many applications, and no noise cross-talk issue found till now.
I will discuss more with you offline.
