Hello,
Im using the DCP010512DBP-U on a board to power up some amp ops. As Im revision this project, I've measured the input current for different capacitors values. I will share my results:
To measure the current, I've used a 1.33Ohm resistor.
In all images, the yellow is the current signal, and blue is the input voltage.
1 - This is the first capacitors values:
Sometimes, after some turn on and offs, this is the signal I got:
2 - So, as the values aboves are not the same the datasheet recomends, I try the following:
3 - Finally, we have this, a little closer to the datasheet:
The 3rd test result in something that I didnt expect, as the capacitances are kinda the same as the datasheet.
Is this results that I've got consistent with the expected operation of this device? Why do I got this long transient on the 3rd circuit?
