Absolute Maximum Ratings are those values beyond which the life
Note 5:
Shunt mode regulation is measured with the input open. With the of a device may be impaired. input connected, shunt mode current can be reduced to 0mA. Load
Note 2:
Output voltage is measured immediately after turn-on. Changes regulation will remain the same. due to chip warm-up are typically less than 0.005%.
Note 6:
RMS noise is measured with a 2-pole highpass filter at 10Hz and a
Note 3:
Temperature coefficient is measured by dividing the change in 2-pole lowpass filter at 1kHz. The resulting output is full-wave rectified and output voltage over the temperature range by the change in temperature. then integrated for a fixed period, making the final reading an average as Separate tests are done for hot and cold; T opposed to RMS. Correction factors are used to convert from average to MIN to 25°C and 25°C to TMAX.

Note 4:
Line and load regulation are measured on a pulse basis. Output Peak-to-peak noise is measured with a single highpass filter at 0.1Hz and a changes due to die temperature change must be taken into account 2-pole lowpass filter at 10Hz. The unit is enclosed in a still-air environment separately. Package thermal resistance is 150°C/W for TO-5 (H), 130°C/W to eliminate thermocouple effects on the leads. Test time is 10 seconds. for N and 150°C/W for the SO-8.
