Regulator in Range 2. RM0444

Where is the truth ?

Both. They're talking about different things. "Range 2" is not "low-power run mode".

Indeed.

@Xme - more details of what regulators are used in which power modes here:

So what is difference? 

it means that when I change voltage scaling to Range 2 while program runs, HCLK can be max 16Mhz .

But when after this I want use WFI(),  the HCLK must be 2MHz max ?

The MCU can be clocked from the normal regular (range 1 or range 2) or the low-power regulator (low power run mode).

Low-power run mode is a lower power consumption mode than either range 1 or range 2.
