Hi,
Just trying to understand something about the TLV757 and the AP7366 - mainly the capacitance for the IN pin.
The datasheet for both components (original; TLV75733P and now the replaced version; AP7366) call for at least 1uF of capacitance on the pin then to ground.
However from what I can see on the schematic here: https://www.pjrc.com/store/teensy40.html - the board doesnt seem to fulfill this requirement. From what I can see there is a combined capacitance of 0.44uF on the IN pin?
I'm in the process of updating my own schematic to implement the newer regulator, but since the datasheets suggest the same for both, I'm confused as to whats going on here? Maybe I'm missing something? Maybe I'm just dumb, or it could even just be an exaggeration that isnt actually required for the regulator that I'm not aware of. If it is just not required to be that high, would meeting that requirement with an additional cap hinder the boards function?
Any help appreciated.
