Symbol
LM3622-XX
Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is in-
tended to be functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics.
Note 2: V
Note 3: Rating is for the human body model, a 100 pF capacitor discharged through a 1.5k
Note 4: The maximum power dissipation must be de-rated at elevated temperatures and is limited by T
(junction-to-ambient thermal resistance) and T
to the value listed in the Absolute Maximum Ratings.
Note 5: Limits reflect initial accuracy.
Note 6: T
