Note 1: Low duty cycle pulse testing with Kelvin connections is required to order to maintain accurate data.
Note 2: Dropout voltage is defined as the minimum differential between V IN and V OUT or V CTRL and V OUT required to
maintain regulation at V OUT 95% Nominal V OUT .
Note 3: V REF is measured across Adjust pin to Sense pin.
