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.

Note 2: Line and load regulation specifications include the effect of self heating.
Note 3: Limit current in or out of Pin 3 to 50nA and capacitance on Pin 3 to 30pF.
