USB_VBUS is a controlled by a Silergy SY6288CCAC-GP 2A Power Distribution Switch. The name of it's enable GPIO signal is USB_PWR_EN. VCC5V is supplied by the main power input called PWR_5V_STB. The name of it's enable GPIO signal is 3V3_5V_EN. VCC3V3, VCC_DDR3_1V5 and VCCK (the CPU power supply) each use a separate Silergy SY8089AAC-GP 2A step down regulator. They are all supplied by the board's main 5V. VCC3V3 and VCC_DDR3_1V5 are fixed regulators while the voltage of VCCK can be changed by changing it's feedback voltage via PWM_C. VCC1V8 is an ABLIC S-1339D18-M5001-GP fixed voltage regulator which is supplied by VCC3V3. VCC_RTC is a Global Mixed-mode Technology Inc. G918T12U-GP LDO which. It is supplied by either VCC3V3 (when the board is powered) or the RTC coin cell battery.
