In a four layer PCB scenario with standard layer stack-up (signal, GND, power, and signal), how do you get power into the power plane?
In my case, there is a voltage regulator sitting on the top layer (SMD) and I need to get power from it into the third layer which is my power plane. Is it enough to put some vias near the output pin of the regulator (or output cap)? It is a mixed digital-analog design. (STM32F4 + some DACs).
