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 V
OUT
has returned to within ±1 percent of V
OUT
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.
