OUTPUT ADJUSTMENT
The REF02 trim terminal can be used to adjust the output
voltage over a 5 V ± 300 mV range. This feature lets the system
designer trim system errors by setting the reference to a voltage
other than 5 V. The output also can be set to exactly 5.00 V or to
5.12 V for binary applications.

Adjustment of the output does not significantly affect the
temperature performance of the device. The temperature
coefficient change is approximately 0.7 ppm/°C for 100 mV of
output adjustment.
