Is it necessary for the ad8232 +Vs to be 2.8V? Can we not give 3 v instead? ( Cardiac monitor configuration)

I'm working on a stationary ECG monitor with the AD8232 as the analog front end. According to the data sheet a +Vs is given but the value isn't specified. Another configuration has a 2.8V +Vs value. But in the eval board I do not see a chip to convert the Vin to 2.8V . What do I do? Is it necessary to step down the voltage? Please advice
