Hello 

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 .
