REF-01/REF-02 Precision Voltage References FEATURES ■ ■ ■ ■ ■ ■ DESCRIPTIO Trimmed Output ±0.3% Low Drift—5ppm/°C Typ Low Noise—3ppm(P-P) High Line Rejection Temperature Output—REF-02 Low Supply Current 1.4mA Max APPLICATIO S ■ ■ ■ ■ ■ 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. , LTC and LT are registered trademarks of Linear Technology Corporation.

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. 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. –V V ∆V = MAX MIN •100 VOUT Note 5: ∆V specification applies trimmed or untrimmed. Note 6: TC is defined as ∆V divided by the temperature range, i.e., ∆V TMAX ± TMIN 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.
