Output Adjustment
The REF01 trim terminal can be used to adjust the volt-
age over a 10V ±300mV range. This feature allows the
system designer to trim system errors by setting the ref-
erence to a voltage other than 10V, including 10.240V for
binary applications (see the Typical Operating Circuit).
Adjustment of the output does not significantly affect the
temperature performance of the device. The tempera-
ture coefficient change is approximately 0.7ppm/°C for
100mV of output adjustment.
Note 1: Guaranteed by design for REF01HP, REF01HSA, REF01CP, REF01CSA, REF01CESA, REF02HP, REF02HSA, REF02CP,
REF02CSA, REF02CESA. Sample tested for all other grades and packages.
Note 2: Line and load regulation specifications include the effect of self heating.
Note 3: ∆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 10V.
Note 4: ∆V
OT
specification applies trimmed to +10.000V or untrimmed.
Note 5: TCV
O
is defined as ∆V
OT
divided by the temperature range.
