VCC filtering
<electronics> A technique for reducing the amount of Radio Frequency
Interference spread via power supply connections. VCC is a common name for the
non-ground power supply line in circuits based on bipolar transistors.
When part of a circuit generates lots of radio-frequency noise, that portion of
the power plane can be isolated from the rest of the circuit and power delivered
to it via a low pass filter, usually a PI filter, as shown in the diagram below.

ground ground
This helps to shield the rest of the circuit from the noise generated by
the load.
