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

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

parameter shall be guaranteed to the limits specified

3. Correction factor of 0.12 added to ceramic capacitors

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

standard limits except where noted

5. 37.5 V Max continuous to be compliant to MIL-HDBK-1547 and Aerospace
