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 25C. 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 = 150C, 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.
