3~8 AMP 5V TO 3.3V VOLTAGE CONVERSION REGULATOR

Contek Microelectronics 

U584/5/7

LINEAR INTEGRATED CIRCUIT

Note 2: Line and load regulation are guaranteed up to the maximum power dissipation(15W for the Contek U584, 10W

for theContek 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.
