I am applying TPS73701 (Adjustable OUT, Set to 3.3V) to my application.
When I checked load regulation of it, result show marginal failure when I apply 0.0005%/mA criteria.
Can you review the test condition and result if the result is valid or not?
Test set-up.
Apply actual use case instead of electric load.
Condition : 90mA<IOUT<783mA
Criteria : 0.005%/mA applied to judge Pass/Fail
Calculation : Referred to Iout=90mA and Vout@90mA
Result
