ASA28XXS Series

Notes to Specifications

1.

Parameter guaranteed and measured during line and load regulation tests.

2.

Bandwidth guaranteed by design. Tested for 20KHz to 2MHz.

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.

5.

An overload is that condition of load in excess of 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

µs and 10µs.

7.

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

8.

Input step transition time between 2

µs and 10µs.

9.

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.
