The REF-02 trim terminal can be used to adjust the output Adjustment of the output does not significantly affect the voltage over a 5V +300mV range. This feature allows the temperature performance of the device. Typically, the tem- system designer to trim system errors by setting the refer- perature coefficent change is 0.7ppm/° C for 100mV of output ence to a voltage other than 5V. Of course, the output can also adjustment. be set to exactly 5.000V or to 5.12V for binary applications.
