NOTES: (1) Minimum supply voltage for REF2912 is 1.8V. (2) Box Method used to determine over temperature drift. (3) Typical value of load regulation reflects

measurements using a force and sense contacts, see text “Load Regulation”. (4) Thermal hysteresis procedure is explained in more detail in Applications Information
