Typical values refer to Tj=25!C. Note 1: Low duty cycle pulse testing with Kelvin con- nections is required in order to maintain accurate data. Note 2: Dropout voltage is defined as the minimum dif- ferential voltage between Vin and Vout required to main- tain regulation at Vout. It is measured when the output voltage drops 1% below its nominal value. Note 3: Minimum load current is defined as the mini- mum current required at the output in order for the out- put voltage to maintain regulation. Typically the resistor dividers are selected such that it automatically main- tains this current. |
