NOTES: (1) Minimum supply voltage for REF3112 is 1.8V.
(2) Box Method used to determine temperature drift.
(3) Typical value of load regulation reflects measurements using force and sense contacts; see the Load Regulation section.
(4) Thermal hysteresis is explained in more detail in the Applications Information section of this data sheet.
(5) For IL > 0, see the Typical Characteristic curves.
