(1)

Parameters identified with boldface type apply at temperature extremes. All other numbers apply at TA = TJ = 25°C. Unless otherwise

specified, all parameters apply for VREF < VOUT < 5.3V.

(2)

Production tested.

(3)

Not production tested. These limits are not to be used to calculate average outgoing quality levels.

(4)

The average temperature coefficient is defined as the maximum deviation of reference voltage at all measured temperatures from TMIN

to TMAX, divided by TMAX − TMIN. The measured temperatures are −55, −40, 0, 25, 70, 85, 125°C.
