Introduction
6.1.2.2
External Regulator Mode
The CC26xx device has an option to be supplied by an external regulator with a voltage range of 1.65 V to
1.95 V. In this mode, the VDDS and VDDR pins are tied together. To enable external regulator mode, the
VDDS_DCDC pin and the DCDC_SW pins must be connected to ground. This effectively disables both
the internal Global LDO and the internal DC/DC regulator. Refer to the reference design for detailed
description of connections and decoupling in this mode.

6.1.3 Digital Power Partitioning
The CC26xx device has two voltage domains, MCU_VD and AON_VD. Both voltage domains contain
multiple power domains, *_PD. Each power domain contains digital modules.
