Minimum supply voltage for REF3012 is 1.8V.

Box Method used to determine over temperature drift.

Typical value of load regulation reflects measurements using a force and sense contacts, see text

Load Regulation.

Thermal hysteresis procedure is explained in more detail in Applications Information section of data sheet.
