Note 1 : Low duty cycle pulse testing with Kelvin connections are required in order to maintain accurate data.
Note 2 : Drop-out 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.
