The REF-01/REF-02 are precision 10V and 5V bandgap
references which provide stable output voltages over a
wide range of operating conditions. Output voltage is
accurate to
鹵0.3%
with a low 5ppm/擄C typical temperature
coefficient. The REF-01 and REF-02 are excellent choices
for applications where low drift, moderate accuracy, low
power consumption and low cost are considerations.
The REF-02 includes a temperature output pin which
provides a linear voltage proportional to absolute tem-
perature.
For lower drift and higher accuracy references, please see
the LT1019 and LT1021 data sheets.
