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 ac-

curate 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 tem-

perature.

For lower drift and higher accuracy references, please see

the LT1019 and LT1021 data sheets.
