Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Electrical specifications do not apply when operating the device

beyond its rated operating conditions.

Note 2: Ratings apply to ambient temperature at 25˚C. Above this temperature, derate the TO92 at 6.2 mW/˚C, and the SOT23-5 at 2.2 mW/˚C. See derating curve

in Operating Condition section..

Note 3: TJ Max = 150˚C, TJ =TA+(θJA PD), where PD is the operating power of the device.

Note 4: Deviation of reference input voltage, VDEV, is defined as the maximum variation of the reference input voltage over the full temperature range.
