Electrical Characteristics
Note 1: Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions under which the device operates
correctly. Operating ratings do not imply guaranteed performance limits. For guaranteed performance limits and associated test conditions, see the Electrical Char-
acteristics.
Note 2: The human body model is a 100pF capacitor discharged through a 1.5k
Note 3: Production testing done at T
Note 4: At elevated temperatures, devices must be derated based on package thermal resistance. The device in the SOT23-3 package must be derated at 4mW/˚C
at ambient temperatures above 70˚C. The device has internal thermal protection.
Note 5: RESET Output for LM809, RESET output for LM810.
