8.6 Voltage Regulators

The following voltage regulators are available in power subsystem:

  • VREG (DC-DC/MLDO):
    • MLDO mode – Linear voltage regulator generating 1.35V for powering CLDO and RF LDO; operates from 1.9–3.6V
    • DC-DC – Switching voltage regulator generating 1.35V; operates from 2.3–3.6V
  • ULP_VREG – Ultra-low-power voltage regulator for operation in back-up mode
  • CLDO, RF LDO – Powering the different blocks of the RF subsystem
  • SOC_LDO – Powering the VDDCORE of the PIC32CX-BZ6
  • PLL_LDO – Supplies 1.2V analog for EPLL(Ethernet PLL) and UPLL (USB PLL)
