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 |
