PISA11

PISA11-Series

Case B: Only one output is loaded

The minimum values for the permissible capacitors are defined with an additional constant current load according to

the parameter list below. During the tests, only one output is loaded and all others are not.

The typical values for the permissible capacitors are defined with an additional resistive load according to the

parameter list below. During the tests, only one output is loaded and all others are not.
