a  Capacitive load may be any value from 0 to the maximum limit without compromising DC performance

b  This parameter shall be guaranteed by design and tested only when there is qualification test and design or process change.

c Load step transition time shall be large than 15μs；

d  Recovery time means that step starts until output voltage comes back to the corresponding ±1%；

e Start up delay time measurement is for a step application of power at the input while power is applied to the input
