STM32H563ZIT6 LDO or SMPS?

Hi,

does the STM32H563ZIT6 have an LDO and/or an SMPS? Contrary to other micros, I cannot find any table or details about it other than the block diagram common to the whole family (screenshot below) and it says "LDO and/or SMPS". Where on the datasheet can I find that information?

Also, on table 14 (second screenshot) which one of the two LQFP columns should I consider (LQFP144 SMPS or LQFP144)?

Datasheet: https://www.st.com/resource/en/datasheet/stm32h563ii.pdf 

Thank you

    Hello,

    On STM32H5 it's either SMPS or LDO contrarily to H7 which has both configurations on the same package.

    This is from the datasheet:

    Q stands for SMPS package:

    In CubeMx:

    SMPS in red, others are LDO.
