Note 1: .“Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is  
functional, but do not guarantee specific performance limits.  
Note 2: Unless otherwise specified, tests are performed at T = 25˚C with pulse testing so that junction temperature does not change during test

Note 3: Set current is the current flowing into the V pin. For the Basic 2-Terminal Current Source circuit shown on the first page of this data sheet. I  
is determined
