Maxim REF01AJ, REF01AZ, REF01CJ, REF01CP, REF01HZ Datasheet
...
General Description
The REF01 and REF02 are precision voltage references
that are pretrimmed to within ±3% of +10V and +5V,
respectively. Both references feature excellent temperature stability (as low as 8.5 ppm/°C worst case), low current drain, and low noise. The REF02 also provides a
TEMP pin whose output voltage varies linearly with temperature, making this device suitable for a wide variety of
temperature-sensing and control applications. Both
devices are available from Maxim in the space-saving SO
package, as well as in the standard 8-pin TO-99 and
MINI-DIP packages.
Features

ABSOLUTE MAXIMUM RATINGS—REF01
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

ELECTRICAL CHARACTERISTICS—REF01
(VIN= +15V, TA= +25°C, unless otherwise noted.)
ELECTRICAL CHARACTERISTICS—REF01
(VIN= +15V, -55°C ≤ TA= +125°C for REF01A and REF01, 0°C ≤ TA≤ +70°C for REF01E and REF01H, IL= 0mA, unless otherwise noted.)
Output Adjustment
The REF01 trim terminal can be used to adjust the voltage over a 10V±300mV range. This feature allows the
system designer to trim system errors by setting the reference to a voltage other than 10V, including 10.240V
for binary applications (see the Typical Operating
Circuit section).
Adjustment of the output does not significantly affect
the temperature performance of the device. The temperature coefficient change is approximately
0.7ppm/°C for 100mV of output adjustment.
