Note 1: Low duty cycle pulse testing with Kelvin connections is required in order to maintain accurate data.
Note 2: Dropout voltage is defined as the minimum differential voltage between VIN and VOUT required to maintain
regulation at VOUT. It is measured when the output voltage drops 1% below its nominal value.
