FEATURES  
DESCRIPTIO  
■
Trimmed Output ±0.3%  
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  
accurateto±0.3%withalow5ppm/°Ctypicaltemperature  
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.  
■
Low Drift—5ppm/°C Typ  
■
Low Noise—3ppm(P-P)  
High Line Rejection  
Temperature Output—REF-02  
■
■
■
Low Supply CurrUent 1.4mA Max  
APPLICATIO S  
The REF-02 includes a temperature output pin which  
provides a linear voltage proportional to absolute tem-  
perature.

Note 1: Absolute Maximum Ratings are those values beyond which the life  
of a device may be impaired.  
Note 2: Line and load regulation specifications include the effect of self  
heating.  
Note 5: ∆V specification applies trimmed or untrimmed.  
Note 6: TC is defined as ∆V divided by the temperature range, i.e.,  
∆V  
TC =  
T
± T  
MAX MIN  
Note 3: Limit current in or out of Pin 3 to 50nA and capacitance on Pin 3  
to 30pF.  
Note 7: 0.1Hz to 10Hz noise cannot be 100% tested on modern high  
speed test equipment, so Linear Technology does not put a guaranteed  
maximum specification on this parameter for standard units. 100% bench  
testing of 0.1Hz to 10Hz noise is available on special request. To ensure  
low output noise, Linear Technology does 100% test 10Hz to 1kHz noise.  
Consult factory for details.  
Note 4: ∆V 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 nominal output.
