LM2733: any restrictions when they use the device at less than 30mA

Tool/software:

Hi team,

Based on Figure 11, there are no information about the efficiency at less than 30mA or so. Does this mean this device can't work properly at the less than 30mA?

Please let us know if there are any restrictions at such a low load current.

Regards,

Noriyuki Takahashi
