There is an internal low-dropout linear voltage regulator to generate a 1.35-V supply rail to power the device core. The core regulator is active in all power modes except for SHUTDOWN. In all other power modes (RUN, SLEEP, STOP, and STANDBY) the drive strength of the regulator is configured automatically to support the max load current of each mode. This reduces the quiescent current of the regulator when using low power modes, improving low power performance.
