Electrical Performance Characteristics - continued Notes to Specifications ATW2812S 1 Parameter guaranteed by line and load regulation tests. 2 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 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. 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% of VOUT at 50% 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 ground signal from the inhibit pin (pin 2) while power is applied to the input.
