Notes to Group A Test Table

1.

Parameter verified during dynamic load regulation tests.

2.

Guaranteed for DC to 20 MHz bandwidth. Test conducted using a 20KHz to 2.0MHz bandwidth.

3.

Deleted

4.

Output is measured for all combinations of line and load.

Only the minimum and maximum readings for the output are

recorded.

5.

Load step transition time

≥ 10µS.

6.

value.

7.

Turn on delay time is tested by application of a logical low to high transition on the enable pin (pin 3) with power present at

the input.

8.

Subgroups 1 and 4 are performed at +25°C, subgroups 2 and 5 at +125°C and subgroups 3 and 6 at -55°C.
