As the fixed voltage for the LDO is outside the range of the adjustable voltage mode, the constraints for this scenario are not suitable to represent both modes. Therefore, A property is added to specify the fixed LDO VOUT. Examples of fixed LDO VOUT and adjustable LDO VOUT is also added to this version.
