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 Curr}U^{ent 1.4mA Max}

APPLICATIO S

The REF-02 includes a temperature output pin which

provides a linear voltage proportional to absolute tem-

perature.
