    Hello Peter,

    The schematic in general looks fine but I have noticed few things.

    • ILIM resistor (11K_F2): I am assuming it to be 1.1K resistor based on ILIM calculations.
    • There is no transient protection. We recommend using some decoupling capacitor (very near the input pin in layout) and a TVS diode for input side transient protection and Schotkey diode at the output side. Events like hot plug and output short causes transients which can very easily exceed the absolute maximum of the device.
