TempDB and User Data Files

I have a Server with 2 Physical Disk and I was wondering if it would be good if We use a distribution like this:

Disk1:

SO (C:\),

DataFiles(user mdf + Tempdb mdf) (E:\)

Disk2:

LogFiles (user ldf + Tempdb ldf) (F:\)

Backups

That would be correct or should I put all the tempdb Files on the Disk2?
