Is the input 15v, can we go off the datesheet?
The datasheet schematics are just examples of how the device can be used in a
particular application. We do not know the voltage used in
this circuit until we can either reference it on a schematic, or trace it back to the source on the PCB. (This is something
you have to help us with)
Ceramic capacitors should be derated by 50%, meaning that if the supply voltage is 10V, the capacitor should be rated to at least 20V.....the closest ratings to 20V are 16V and 25V. Obviously, 16V is below, so the next value which is above 20V, would be 25V.
If the supply voltage is 12V, twice that is 24V and it might be better to step up to the next value, which is 35V.
In your other threads, you indicate that you have measured 10V and 15V at some points on the PCB, and it may be that this section of the PCB is indeed supplied with 10V or 15V, but in order to correctly verify, this particular section should be checked with a volt-meter, or visually traced back to the source.
Please understand that we do not have the PCB in front of us, so we are reliant upon the information that you can provide us.
We don't like to guess.
