Notes to Specifications (Single Output Models)

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 necessary to trigger the short circuit protection and is the condition of maximum

power dissipation.

5. Load step transition time between 2 to 10 microseconds.

6. Recovery time is measured from the initiation of the transient to where V

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 inhinbit pin (pin 2) while power is

applied to the input. Above 125

°C case temperature, derate output power linearly to 0 at 135°C case.
