VCC
From bildr
VCC (supply voltage) is used to denote the positive voltage supply in a circuit. This may come directly from a battery or other power source, or may be the output of a voltage regulator. In modern CMOS circuitry VDD is sometimes also used to denote the positive supply.
(VCC stands for Voltage at Common Collector)
