Note 1: Load and line regulation are measured at a constant junction temperature by low duty cycle pulse testing. UTC UNISONIC TECHNOLOGIES CO., LTD. 2 QW-R102-003,A UTC U584/5/7 LINEAR INTEGRATED CIRCUIT Note 2: Line and load regulation are guaranteed up to the maximum power dissipation(15W for the UTC U584, 10W for the UTC U585). Power dissipation is determined by input / output differential and the output current. Guaranteed maximum output power will not be available over the full input-output voltage range. Note 3: IFULLLOAD is defined as the maximum value of output load current as a function of input-to-output voltage. Output current can be different for different input-to-output voltage.
