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.
