C8051F80x-83x
11. Voltage Regulator (REG0)
C8051F80x-83x devices include an internal voltage regulator (REG0) to regulate the internal core supply
to 1.8 V from a V
supply of 1.8 to 3.6 V. A power-saving mode is built into the regulator to help reduce
DD
current consumption in low-power applications. This mode is accessed through the REG0CN register
(SFR Definition 11.1). Electrical characteristics for the on-chip regulator are specified in Table 7.5 on
page 41
Under default conditions, when the device enters STOP mode the internal regulator will remain on. This
allows any enabled reset source to generate a reset for the device and bring the device out of STOP mode.
For additional power savings, the STOPCF bit can be used to shut down the regulator and the internal
power network of the device when the part enters STOP mode. When STOPCF is set to 1, the RST pin or
a full power cycle of the device are the only methods of generating a reset.
