ELECTRICAL CHARACTERISTICS

Note 1: Absolute Maximum Ratings are those values beyond which the life

of a device may be impaired.

Note 2: Selected devices with guaranteed maximum temperature

coefficient are available upon request.

The q denotes the specifications which apply over the full operating

temperature range, otherwise specifications are at TA = 25°C. For the LM185-1.2 TMIN = –55°C and TMAX = 125°C. For LM285-1.2

TMIN = –40°C and TMAX = 85°C.For LM385-1.2 TMIN = 0°C and TMAX = 70°C. For MIL-STD components, please refer to LTC883C data

sheet for test listing and parameters.
