OUTPUT ADJUSTMENT
The REF02 trim terminal can be used to adjust the output
voltage over a 5 V
±300 mV range. This feature allows the sys-
tem designer to trim system errors by setting the reference to a
voltage other than 5 V. Of course, the output can also be set to
exactly 5.000 V, or to 5.12 V for binary applications.

Figure 2. Output Adjustment Circuit
Adjustment of the output does not significantly affect the tem-
perature performance of the device. The temperature coefficient
change is approximately 0.7 ppm/
∞C for 100 mV of output
adjustment.
