7.6 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

  • RF LDO – Powering the different blocks of the RF subsystem

  • CLDO – Powering the VDDCORE of PIC32CX-BZ3
