The Voltage Reference provides a precise output voltage, one that is much more accurate than a voltage regulator. The output voltage is then compared to other voltages in the systems. It is just that, a reference. It is not used for power functions, but to provide the system with an accurate analog voltage for comparison purposes, even when the system experiences a large temperature change.
References are similar to regulators in how they function, but they are used much differently.
Only a few references have the capability to deliver a load greater than a few milliamps while maintaining a precision output voltage. References serve as a comparison point for the analog input voltage from the A to Ds and the analog output voltage from the D to As. They are also commonly used in battery chargers.
