Notes:
1/
Parameter guaranteed by line load, and cross regulation tests.
2/
Up to 90 percent of full power is available from either output provided the total output does not exceed 12 W.
3/
Bandwidth guaranteed by design. Tested for 20 kHz to 2 MHz.
4/
Load current split equally between +VOUT and -VOUT.
5/
1.2 watt load on output under test, 1.2 watt to 10.8 watt load change on other output.
6/
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.
7/
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 VI.
8/
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.
9/
Load step transition time between 2 and 10 microseconds.
10/ 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.
11/ Input step transition time between 2 and 10 microseconds.
12/ 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 1) while
power is applied to the input.
