OUTPUT ADJUSTMENT
The REF02 trim terminal can be used to adjust the voltage
over a 5V
±
150mV range. This feature allows the system
designer to trim system errors by setting the reference to a
voltage other than 5V, including 5.12V
(1)
for binary applica-
tions (see circuit on page one).
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.
NOTE: (1) 20mV LSB for 8-bit applications.

REFERENCE STACKING
PROVIDES OUTSTANDING LINE REGULATION
By stacking two REF01s and one REF02, a systems designer
can achieve 5V, 15V and 25V outputs. One very important
advantage of this circuit is the near perfect line regulation at
5V and 15V outputs. This circuit can accept a 27V to 55V
change to the input with less than the noise voltage as a
change to the output voltage. (R
B
), a load bypass resistor,
supplies current (I
SY
) for the 15V regulator.
Any number of REF01s and REF02s can be stacked in this
configuration. If ten devices can be stacked in this configu-
ration, for example, ten 5V or five 10V outputs are achieved.
The line voltage may range from 100V to 130V. Care should
be exercised to insure that the total load currents do not
exceed the maximum usable current which is typically
21mA.
