LINEAR INTEGRATED CIRCUIT
The * denotes specifications which apply over the specified operating temperature range.
Note 1: Load and line regulation are measured at a constant junction temperature by low duty cycle pulse testing.
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.
