Dear Team.
the application section of the TPS82084/5 data sheet states that an output capacitor should be below 150uF.
We are interested in the devices for 3 different voltage rails on an FPGA board. All rails are buffered by different capacitors on the board.
Measurements with the prototype give following details:
1.8V -> 200µF
1.0V -> 70µF
1.1V -> 151µF
The 1.8V and 1.1V are above the recommendation (excl. actual output cap at the TPS).
Do you see an issue with running the devices at a higher capacitive load?
Would it be acceptable if the start-up current is limited / under control?
Do you maybe have more data about the stability / start-up with higher capacitive loads available?
Any feedback is very much appreciated.
Best Regards
Martin
