NOTES: (1) Minimum supply voltage for REF3012 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 section of data sheet.
(5) For IL > 0, see Typical Characteristic curves.
