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

standard limits except where noted

4. Correction factor of 0.12 added to ceramic capacitors

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