Voltage regulator in STM32f4x

Posted on May 02, 2018 at 06:06

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 .
