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.
