Hi Eric,

I would be happy to review your schematic. Before doing so I would advise that you review the datasheet and EVM guide for any suggestions. If you feel comfortable, you can send the schematic through a private message or email.

Hi Eric,

Thanks for providing your schematic and taking the time to look through our application guides. I will take a look at this and provide your feedback as soon as I can.

Hi Eric,

I reviewed your schematic and for the most part everything seems correct. Although, I am curious why are there are zero ohm place holders for pull-down resistors on the EN1/EN2 pins. There is already internal pull-downs that can be disabled and enabled, they are enabled by default. Hence, I am assuming you are using i2c to enable/disable the regulators. Also, I would recommend adding a .1uF capacitor in parallel on each one of your output rails. The 22uF capacitor probably has a high ESR, which you can minimize using a small .1uF capacitor. It can usually help by improving your transient response.
