VDDH

[A.P]

Hi!

I looked at the specifications, and it doesn't seem like this is listed as not possible, but it strikes me like it should not be possible, so I wanted to make sure.
Looking at the Electrical Specification section for the regulators, it looks like the limitation for VDD is 1.7V<VDD<3.6V and for VDDH is 2.5V<VDDH<5.5V. They do not seem co-dependent.
Ok, but can I use the regulator to increase the voltage I'm getting in VDDH?

An example:

VDDH is set to 3.0V, and I want to set VDD to 3.3 V using regulator1- higher than VDDH.
is this possible?

Thanks!

Hi,

the chip has LDO and buck (step-down) regulators, both can provide output voltage only lower than input.
