Hi. What is the current consumed by VCORE, or VDDLDO (if using internal regulator) for STM32H750XB?

From datasheet, section 6.1.7, fig 10 Current consumption measurement scheme, the IDD is shown to include only current drawn by VDD and VDDA pins. And in Table 28 (Typ and max current consumption...) the current consumption numbers are for IDD only. Does this IDD (in Table 28) includes VCORE/VDDLDO? Thanks.

ST should confirm and the update the documents but ​I believe it includes VCORE/VDDLDO.

If you look at the sleep current, the core will be clock gated or powered off. This gives you an idea of how much power the peripherals consume with not much going on. These are much, much lower than the power consumption in the table with the core speeds.

Thanks, Harjit. I thought so too, but would like to confirm, since CORE typically consumes a lot more power than peripherals, and it'd be hard to make up for CORE consumption if it's not accounted for in power supply design.
