Notes:
[1] Please refer to the Part Number Structure when ordering.
[2] All specifications are at nominal line voltage and full load, +25C unless otherwise noted. See detailed specifications. Output capacitors are 1F ceramic multilayer in parallel with
10F. I/O caps are necessary for our test equipment and may not be needed for your application.
[3] Regulation specifications describe output voltage deviations from a nominal/midpoint value to either extreme (50% load step).
