7.2.3 Voltage Regulator

The PIC32CK SG/GC internal Main Voltage Regulators have three different modes, controlled by the Power Manager (PM).

  • Enabled mode: This is the default mode when CPU and peripherals are running.
  • Low-Power mode: This is the mode when CPU and peripherals are in standby.
  • Disabled mode: When the chip is in backup mode, the internal regulator is off, the VDDCORE_SW core power domain is OFF. The VDDCORE_BU backup domain is powered by the backup regulator (LPVREGC).
