Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is

intended to be functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics

. The

guaranteed specifications apply only for the test conditions listed.

Note 2: Thermal resistance is as follows:

165°C/W

Note 3: Parameters identified with boldface type apply at temperature extremes. All other numbers apply at TA = TJ = 25°C.

Note 4: Guaranteed and 100% production tested.

Note 5: Guaranteed but not 100% production tested. These limits are not used to calculate average outgoing quality levels.

Note 6: The average temperature coefficient is defined as the maximum deviation of reference voltage at all measured temperatures between the operating TMAX and

TMIN, divided by TMAX - TMIN. The measured temperatures are 0

°C, 25°C, 70°C.
