Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: VKA is the cathode voltage of the LT1431CZ/IZ and corresponds
to V+ of the LT1431CN8/IN8/CS8/IS8. IK is the cathode current of the
The l denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at TA = 25°C. IK = 10mA unless otherwise specified (Note 2)

LT1431CZ/IZ and corresponds to I(V+) + ICOLLECTOR of the LT1431CN8/
IN8/CS8/IS8.
Note 3: The LT1431 has bias current cancellation which is effective only
for VKA ≥ 3V. A slight (≈2mV) shift in reference voltage occurs when
VKA drops below 3V. For this reason, these tests are not performed at
VKA = VREF.
