What is a series regulator with 2 output functions?

This is a series regulator that outputs two different output voltages from an input voltage (in single package).

Example: The UPC37Mxx Series consists of regulators that have two output functions, OUTPUT1 (3.3 V or 2.5 V): 1 A and OUTPUT2 (1.8 V or 2.5 V): 0.5 A.
