I'm designing a circuit using an LDO voltage regulator; specifically the LD39130SPUR from ST. This variant of the part allows for an adjustable output voltage via a potential divider as seen on page 8 of the datasheet. Usually, when using adjustable LDOs and other similar parts, a formula is provided to calculate the output voltage.
My issue is that I can't seem to find any such formula or other information that will allow me to calculate the output voltage. Am I missing something? Or, is there a 'standard' formula used to calculate this sort of thing given specific input parameters?
I'm looking to achieve a voltage of ~3.5V.
