Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: Unless otherwise specified, tests are performed at T
j
 = 25癈 with
pulse testing so that junction temperature does not change during test.
Note 3: Set current is the current flowing into the V
+
 pin. It is determined
by the following formula: I
SET
 = 67.7mV/R
SET
 (at 25癈). Set current error
is expressed as a percent deviation from this amount. I
SET
 increases at
0.336%/癈 at T
j
= 25癈.
Note 4: I
SET
 is nominally directly proportional to absolute temperature
(癒). I
SET
 at any temperature can be calculated from: I
SET
 = I
O
 (T/T
O
)
where I
O
 is I
SET
 measured at T
O
 (癒).
Note 5: V
MAX
 = 40V for LM134 and 30V for other grades.
