... The LM3354 is available in a 10-pin MSOP package. This package has a maximum height of only 1.1 mm. The high efficiency of the LM3354, low operating and shut- down currents, small package size, and the small size of the overall solution make this device ideal for battery powered, portable, and hand-held applications ...

... Maximum Load Under Start-Up Due to the LM3354’s unique start-up sequence not able to start up under all load conditions. Starting with less will allow the part to start correctly under any tempera- ture or input voltage conditions. After the output is in regu- lation, any load up to the maximum as specified in the Electrical Characteristics may be applied ...
