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

of a device may be impaired.

Note 2: All specifications are for TA = 25°C unless otherwise noted. For the

LM185-2.5 TMIN = – 55°C and TMAX = 125°C. For LM285-2.5, TMIN = –

°C and TMAX = 85°C. For LM385-2.5, TMIN = 0°C and TMAX = 70°C.

Note 3: For very low initial tolerance, consult LT1004 data sheet. The

LT1004 is a low cost, pin for pin substitution device. For guaranteed

temperature coefficient consult the LT1034-2.5 data sheet.

Note 4: Guaranteed but not tested.

The q denotes the specifications which apply over the full operating

temperature range, otherwise specifications are at TA = 25°C. (Note 2)
