Output Load Transient Response
Output voltage response to load current step-
change (3.75-11.25-3.75 A) at:
T
Active adjust
The output voltage may be adjusted using a {current/voltage} applied to the
Vadj pin. This {current/voltage} is calculated by using the following equations:
Example: Upwards => 5.1 V
Example: Downwards => 4.9 V
