    Hi JH,

    See my comments below:

    1. Recommend to add a feedforward capacitor (parallel with upper resistor), for example 47pF.

    2. EN can be controlled by a typical divider resistor circuit from Vin or by a voltage of lower than 5.5V. In the schematic, I see both typical divider resistor and external EN signal exist. I think one of them will be good.

    Thanks!
