1 Parameter guaranteed by line and load regulation tests.

2 Bandwidth guaranteed by design. Tested for 20 KHz to 2.0 MHz.

3 Output voltage measured at load with remote sense leads connected across load.

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. Parameters shall be guaranteed

to the limit specified in Electrical Specifications.

6 Load step transition time between 2.0 and 10 microseconds.

7 Recovery time is measured from the initiation of the transient to where V

8 Input step transition time between 2.0 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 while power is applied to the input.
