Hi!

I am working with LMR16006Y first time, and I need help in assessing the correctness of the layout of the circuit. All parts were calculated according datasheet with output current less than 100mA.

I think your schematic and layout are fair.

I have the following comments:

1. I would increase the value of C12/16 to 10uF

2. Need many more ground vias around C12/16, D4/5, C14/18 and the ground of the device. This will help to connect the grounds better.

3. Connect top of R3/6 closer to C12/16

4. Use as wide a trace as possible to pin2 ground.
