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 5.000 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 m

TEMPERATURE MONITORING
As described previously, the REF02 provides a TEMP output
(Pin 3) that varies linearly with temperature. This output can be
used to monitor the temperature change in the system. The
voltage at VTEMP is approximately 550 mV at 25°C, and the
temperature coefficient is approximately 1.96 mV/°C (see

Figure 18. Voltage at TEMP Pin vs. Temperature
A voltage change of 39.2 mV at the TEMP pin corresponds to a
20°C change in temperature.
The TEMP function is provided as a convenience rather than a
precise feature. Since the voltage at the TEMP node is acquired
from the band gap core, current pulling from this pin will have
a significant effect on VOUT. Care must be taken to buffer the
TEMP output with a suitable low bias current op amp, such as
the AD8601, AD820, or OP1177 (all of which would result in
buffering, even tens of microamps drawn from the TEMP pin
can cause VOUT to fall out of specification.
