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 Tj = 25C 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. ISET is
determined by the following formula: ISET = 67.7 mV/RSET (@ 25C). Set current error is expressed as a percent deviation from this amount. ISET increases at
0.336%/C @ Tj = 25C (227 V/C).
Note 4: ISET is directly proportional to absolute temperature (K). ISET at any temperature can be calculated from: ISET =Io (T/To) where Io is ISET measured at To
(K).
Note 5: For elevated temperature operation, TJ max is:
