Hi,
using the TPS7A52-Q1 to have a stable 1,95V voltage at the Output. Supply it with stable 5V from another LDO.
On my first PCB where I designed it on I see that it is quite often showing the correct 1,95V (without load). Sometimes I see when making Tests with Multimeter/Oszi that the Output Shows more than the 1,96V (2...2,5V) and going then down to the 1,95V.
With a load (another digital device which Needs 1,95V) I see that it is going up to 2,59V?! (stable).
I dont know why.
Here is the schematic:
Does anybody have an idea whats Happening here?
Thanks,
Markus
