ATR28XXS Series

ATR2815S

Notes to Specifications

1

Parameter guaranteed by line and load regulation tests.

2 Bandwidth guaranteed by design. Tested for 20KHz to 2.0MHz.

3

Output voltage measured at load with remote sense leads connected across load.

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. There after parameters shall be

guaranteed to the limits specified in table IV.

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 condition of maximum power dissipation.

7 Load step transition time between 2.0

µs and 10µs.

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

9 Input step transition time between 2.0

µs and 10µs.

10 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 (pin2) while power is applied to the input.
