I have found a PMIC - Voltage Regulator TPS74401KTWR in

Is it possible for me to adjust Output voltage by using this regulator? And what's the voltage-regulation principle? I have read its relevant pdf, but I still don't understand. Can anyone help me to comprehend it better?

Any answers will be appreciated! ;)
