The filter output is then rectified and integrated for a fixed time period, resulting in an average, as opposed to RMS voltage. A correction factor is used to convert average to RMS. This value is then used to obtain RMS noise voltage in the 10Hz to 1000Hz frequency band. This test also screens for low frequency "popcorn" noise within the bandwidth of the filter. Consult factory for 100% 0.1Hz to 10Hz noise testing. Note 6: Devices typically exhibit a slight negative DC output impedance of – 0.015 Ω. This compensates for PC trace resistance, improving regulation at the load. Note 1: Absolute Maximum Ratings are those values beyond which the life of the part may be impaired. Note 2: Output voltage is measured immediately after turn-on. Changes due to chip warm-up are typically less than 0.005%. Note 3: Temperature coefficient is determined by the "box" method in which the maximum ∆VOUT over the temperature range is divided by ∆T. Note 4: Line and load regulation measurements are done on a pulse basis. Output voltage changes due to die temperature change must be taken into account separately. Package thermal resistance is 150 °C/W for TO-5 (H), 130 °C/W for PDIP (N8), and 180°C/W for plastic SO (SO-8).
