ELECTRICAL CHARACTERISTICS–REF02 (continued)
(V IN = +15V, T A = T MIN to T MAX , I L = 0mA, unless otherwise noted.)
Note 5: Guaranteed by design.
Note 6: Line and load regulation specifications include the effect of self heating. 100% production tested at T A = +25°C and guaranteed
by design for T A = T MIN to T MAX , as specified.
Note 7: Limit current in or out of pin 3 to 50nA and capacitance on pin 3 to 30pF.
Note 8: ? V OT is defined as the absolute difference between the maximum output voltage and the minimum output voltage over the
specified temperature range expressed as a percentage of 5V. Guaranteed by design.
? V -V ?
5V
Note 9: TCV O is defined as ? V OT divided by the temperature range. Guaranteed by design.
Output Adjustment
880
The REF02 trim terminal can be used to adjust the out-
put voltage over a 5V ±300mV range. This feature
allows the system designer to trim system errors by set-
ting the reference to a voltage other than 5V (refer to
the Typical Operating Circuit ).
Adjustment of the output does not significantly affect
the temperature performance of the device. Typically,
the temperature coefficient change is 0.7ppm/°C for
100mV of output adjustment.

The REF02 provides a temperature-dependent output
voltage on the TEMP pin. This voltage is proportional to
-60 -40 -20
0 20 40 60 80 100 120 140
TEMPERATURE ( ° C)
the absolute temperature, and has a scale factor of
approximately 2.1mV/°C (Figure 1).
Output Voltage = 2.1(T + 273)mV
where T = Temperature in °C.
