    Hi Sherry,

    Thanks for your questions.

    A couple of comments:

    - The Recommended Operating conditions specifies a maximum input voltage of 6V and your nominal input voltage is pretty close (5.8V). The customer should guarantee that the input voltage is lower than 6V across operating conditions (transients, T, tolerance, ..), to guarantee proper functionality and reliability.

    - Is R1103_B (the 10 Ohm resistor) placed for bode plot measurements? If this is the case, the customer should connect the feedforward capacitor (C1103_B), before the resistor (therefore to P1103_D, in parallel to R1103_C).

    - I would advise to use 22pF as C1103_B. However, this value can be optimized in the lab to get optimal transient response.

    Thanks,
    Stefano
