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
