4.1.1 Core Voltage Regulator

The core voltage regulator is managed by the Supply Controller (SUPC). It features three operating modes:

In Normal mode, internal adaptive biasing adjusts the regulator quiescent current depending on the required load current.
In Wait mode, the regulator is still ON but in low power mode with a very low quiescent current.
In Backup mode, the voltage regulator is OFF.
