Notes:
1. Bandwidth guaranteed by design. Tested for 20 KHz to 2 MHz.
2. Capacitive load may be any value from 0 to the maximum limit without affecting dc performance. A capacitive load in excess of the maximum limit will not disturb loop stability
but will interfere with the operation of the load fault detection circuitry, appearing as a short circuit during turn-on.
3. Parameter shall be tested as part of design characterization and after design or process changes. Thereafter shall be guaranteed to the limits specified.
4. 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.
5. Load step transition time between 2 and 10 microseconds.
6. Recovery time is measured from the initiation of the transient to where VOUT has returned to within ±1 percent of VOUT at 50 percent load.
7. Input step transition time between 2 and 10 microseconds.
8. Turn on delay time measurement is for either a step application of power at input or the removal of a ground signal from the inhibit pin (pin 2) while power is applied to the
input.
9. Above 125°C case temperature, derate output power linearly to 0 at 135°C case.
