1. Half load at +Vout and half load at -Vout

2. Up to 60% of the total power or current can be drawn from either of the two

outputs

3. Time for output voltage to settle within 1% of steady-state value

4. Verified by initial electrical design verification. Post design verification,

parameter shall be guaranteed to the limits specified

5. End-of-Life performance includes aging and radiation degradation and is within

standard limits except where noted

6. Correction factor of 0.12 added to ceramic capacitors

7. 37.5 V Max continuous to be compliant to MIL-HDBK-1547 and Aerospace TOR

8. 5% load to full load at -55 °C
