I am using stm32f446re nucleo board and trying out some power saving code .
in RM i found this
Bit 0 LPDS: Low-power deepsleep
This bit is set and cleared by software. It works together with the PDDS bit.
0:Main voltage regulator ON during Stop mode
1: Low-power voltage regulator ON during Stop mode
Does this mean , this MCU has 2 voltage regulators ? one is main voltage regulator and another one is low power voltage regulator .
where can i get info about both the regulators ? preferably block diagrams .
