17. Voltage Regulator (VREG0)
C8051F93x-C8051F92x devices include an internal voltage regulator (VREG0) to regulate the internal
core supply to 1.8 V from a VDD/DC+ supply of 1.8 to 3.6 V. Electrical characteristics for the on-chip
regulator are specified in the Electrical Specifications chapter.
The REG0CN register allows the Precision Oscillator Bias to be disabled, reducing supply current in all
non-sleep power modes. This bias should only be disabled when the precision oscillator is not being used.
The internal regulator (VREG0) is disabled when the device enters sleep mode and remains enabled when
the device enters suspend mode. See Section “14. Power Management” on page 156 for complete details
about low power modes.

When set to 1, the bias used by the precision oscillator is forced on. If the precision
oscillator is not being used, this bit may be cleared to 0 to save approximately 80 µA
of supply current in all non-Sleep power modes. If disabled then re-enabled, the pre-
cision oscillator bias requires 4 µs of settling time.
