DESCRIPTIO

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 ±0.3% with a low 5ppm/°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 tem­perature.

For lower drift and higher accuracy references, please see
the LT1019 and LT1021 data sheets.
