Note 1 : Low duty cycle pulse test with Kelvin con-
nections are required to maintain data accuracy .
Note 2 : Dropout voltage is defined as the minimum
difference between VIN and VOUT required to maintain
1% VOUT regulation .
Note 3 : Minimum load current is defined as the mini-
mum current required at the output to maintain VOUT
regulation.
