Note 1:
V
KA
is the cathode voltage of the LT1431CZ/IZ and corresponds to
V

of the LT1431CN8/MJ8. I

COLLECTOR
of the LT1431CN8/MJ8/IN8.
Note 2:
The LT1431 has bias current cancellation which is effective only
for V
KA
≥
3V. A slight (
≈
2mV) shift in reference voltage occurs when
V
KA
drops below 3V. For this reason, these tests are not performed at
V

= V
