Bandwidth guaranteed by design. Tested for 20KHz to 2.0MHz. 3. Capacitive load may be any value from 0 to the maximum limit without compromising dc performance. A capacitive 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 II. 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 2.0 µs and 10µs. 7. Recovery time is measured from the initiation of the transient to where V OUT has returned to within ±1.0 percent of V OUT at 50 percent load. 8. Input step transition time between 2.0 µs and 10µs. 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 1) while power is applied to the input is unlimited.
