FEATURES
DESCRIPTION
n
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.

APPLICATIONS
The REF-02 includes a temperature output pin which
provides a linear voltage proportional to absolute tem-
perature.

ELECTRICAL CHARACTERISTICS
Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 5: ΔV specification applies trimmed or untrimmed.
Note 6: TC is defined as ΔV divided by the temperature range, i.e.,
ΔV
TC =
T
– T
MAX MIN
Note 2: Line and load regulation specifications include the effect of self
heating.
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 3: Limit current in or out of Pin 3 to 50nA and capacitance on Pin 3
to 30pF.
Note 4: ΔV 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.
