The resulting output is full wave rectified Note 2: Temperature coefficient is measured by dividing the change in and then integrated for a fixed period, making the final reading an average output voltage over the temperature range by the change in temperature. as opposed to RMS. Correction factors are used to convert from average Separate tests are done for hot and cold; T to RMS and to correct for the nonideal bandpass of the filters. Peak-to- MIN to 25°C and 25°C to TMAX.

With Note 8: IOUT(MAX) (Sourcing) is 5mA for exposures greater than the input connected, shunt mode current can be reduced to 0mA. Load 100Krad (Si). regulation will remain the same. Note 9: VIN = 12V, IOUT = 0, unless otherwise noted. Note 10: Absolute Maximum Ratings are those values beyond which the life of a device may be impaired.
