Reddy,
the part markings on the package lists the voltage.
First line is the part number second line is the voltage. If it says ADJ then it's an adjustable version, if it says 1.0V is for the 1V version.
you schematics is missing a couple of components on the feedback.
Also I see you used different value components (2x47uF after each inductor is recommended)
Best Regards,
