Notes to Specifications
1 Parameter guaranteed by line and load regulation tests.
2 Bandwidth guaranteed by design. Tested for 20kHz to 2.0MHz.
3 For operation at 16 Vdc input, derate output power by 33%.
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 2.0µs 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
ground signal from the inhibit pin (pin 2) while power is applied to the input.
