Note 5 : Low duty cycle pulse test with Kelvin connections are required to maintain data accuracy .
Note 6 : Dropout voltage is defined as the minimum difference between VIN and VOUT required to maintain 1% VOUT
regulation.
Note 7 : Minimum load current is defined as the minimum current required at the output to maintain VOUT regulation.
