(1)

Box Method used to determine overtemperature drift.

(2)

Typical value of load regulation reflects measurements using a force and sense contacts, see Load Regulation.

(3)

Minimum supply voltage for REF2912 is 1.8 V.

7.5 Electrical Characteristics

Boldface limits apply over the specified temperature range, TA = –40°C to 125°C. At TA = 25°C, ILOAD = 0 mA, VIN = 5 V,

unless otherwise noted.
