    Hi Ishii-san, 

    Considering the 100uF output capacitor the application has, 350mA seems to be reasonable. Here is an app note that discusses ways to control the in-rush. In the app note, http://www.ti.com/lit/an/slva670a/slva670a.pdf, Figure 4 shows an example of an LDO without in-rush control, with 100uF, the in-rush is as high as 6.4A. 

    The current limit of this device could be over 300mA, having a peak current at 350mA for a short period of time will not damage the device. However, constantly running the device at the current limit may reduce the reliability of the device. 

    Regards,
