Note 1:
Absolute Maximum Ratings are those values beyond which the life
Note 5:
RMS noise is measured with an 8-pole bandpass filter with a of the part may be impaired. center frequency of 30Hz and a Q of 1.5. The filter output is then rectified and integrated for a fixed time period, resulting in an average, as opposed
Note 2:
Output voltage is measured immediately after turn-on. Changes to RMS voltage. A correction factor is used to convert average to RMS. due to chip warm-up are typically less than 0.005%. This value is then used to obtain RMS noise voltage in the 10Hz to 1000Hz
Note 3:
Temperature coefficient is determined by the "box" method in frequency band. This test also screens for low frequency "popcorn" noise which the maximum ∆VOUT over the temperature range is divided by ∆T. within the bandwidth of the filter. Consult factory for 100% 0.1Hz to 10Hz
Note 4:
Line and load regulation measurements are done on a pulse basis. noise testing. Output voltage changes due to die temperature change must be taken into
Note 6:
Devices typically exhibit a slight negative DC output impedance of account separately. Package thermal resistance is 150°C/W for TO-5 (H), – 0.015Ω. This compensates for PC trace resistance, improving regulation 130°C/W for PDIP (N8), and 180°C/W for plastic SO (SO-8). at the load.
