Notes:
1. Cold Start and 25°C
2. Test by dc loading side parallel with a 0.1uF ceramic capacitor and
measured band-width with DC-20MHz.
3. Regulation includes line, cross temperature drift, tolerance variation
Load regulation measured from 20% to Full load. All other outputs
at nominal load.
4. No termination necessary with Control pin to maintain constant ”On”
operation.

7. FR: 80MHz-2.5GHz; Field Strength 3V/M
8. 95% 250Cy , 70% 25Cy, 40% 5Cy, 5% 0.5Cy
9. MIL STD 217, 25°C
10. Tested with shippinjg container for 30 minutes
11. Measured at nominal load with the other output(s) varied between
20% and 100% nominal load.
