Notes to Specifications
1 Parameter guaranteed by line and load regulation tests.
2 Bandwidth guaranteed by design. Tested for 20KHz to 2.0MHz.
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. There after parameters shall be
guaranteed to the limits specified in table II.
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 2.0µs and 10µs.
8 Recovery time is measured from the initiation of the transient to where V_OUT has returned to within ±1.0% of V_OUT at 50% load.
9 Input step transition time between 2.0µs and 10µs.
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.
