NOTES:
(a) Output change with temperature
The absolute maximum difference between the
maximum output voltage and the minimum output
voltage over the specified temperature range:
(b) Output temperature coefficient (T
The ratio of the output change with temperature to the
specified temperature range expressed in ppm/°C:
(c) Operating current (I
Maximum operating current must be derated as
indicated in maximum ratings.
