Notes:
1/
Parameter guaranteed by line and load regulation tests.
2/
Bandwidth guaranteed by design. Tested for 20 kHz to 2 MHz.
3/
Capacitive load may be any value from 0 to the maximum limit without compromising dc performance. A capacitive load in excess of the
maximum
limit will not disturb loop stability but may interfere with the operation of the load fault detection circuitry, appearing as a short circuit during turn-
on.
4/ Parameter shall be tested as part of design characterization and after design or process changes. Thereafter, parameters shall be guaranteed to the
limits specified in Table III.
5/ An overload is that condition with a load in excess of the rated load but less than that necessary to trigger the short circuit protection and is the
condition of maximum power dissipation.
6/
Load step transition time between 2 and 10 microseconds.
7/
Recovery time is measured from the initiation of the transient to where VOUT has returned to within ±1 percent of VOUT at 50 percent load.
8/
Input step transition time between 2 and 10 microseconds.
9/
Turn-on delay time measurement is for either a step application of power at the input or the removal of a ground signal from the inhibit pin (pin 2)
while power is applied to the input.
