1. Half load at +Vout and half load at -Vout
5. End-of-Life performance includes aging and radiation degradation and is within
standard limits except where noted
6. 5% load to full load at -55 °C
2. Up to 70% of the total power or current can be drawn either of the two outputs
3. Time for output voltage to settle within 1% of steady-state value
4. Verified by qualification testing
7. Derate linearly to 0 at 135 °C
