    Hi Luck,
    Thanks for using our device! For better review feedback, could you share us more clear schematics? like a PDF version? The current one is not clear enough to make any good feedback.

    Luck,

    I looked over your schematic and I only have a couple of notes.

    1. I would recommend change your inductors to 0.47uH. The device is validated using 0.47uH inductors, and while more inductance can work, it likely won't be as stable.
    2. I see you are not utilizing the nINT pin. This is not absolutely required, but it can be very helpful to have your device that is configuring the LP873300-Q1 monitoring this pin.
    3. It might also be a good idea to add another 2.2uF and 4.7uF cap to the LDO inputs, just to ensure the LDOs are stable.

    Please let me know if you need anything else.
