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 Tj = 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. It is determined
by the following formula: ISET = 67.7mV/RSET (at 25°C). Set current error

is expressed as a percent deviation from this amount. ISET increases at
0.336%/°C at Tj = 25°C.
Note 4: ISET is nominally 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: VMAX = 40V for LM134 and 30V for other grades.
