Notes:
1/ Parameter guaranteed by line and load regulation tests.
2/ Bandwidth guaranteed by design. Tested for 20 KHz to 2 MHz.
3/ For operation at 16 V dc input, derate output power by 33 percent.
4/ 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.
5/ 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.
6/ 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.
7/ Load step transition time between 2 and 10 microseconds.
8/ 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.
9/ Input step transition time between 2 and 10 microseconds.
10/ 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.
