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..
