Hi,

What are the Pros and Cons of Analog LDO and Digital LDO in-case of AXP803 ?

Is there any limitations such a using them for certain interfaces/applications only ??


Awaiting your reply.

Analog LDOs are for analog circuit such as PLL, video, and audio. Digital LDOs are for digital circuit. Both as its own ground plane so that digital noise will not easily couple over to analog and cause analog noise.

For limitation, please study the APX803 datasheet at PINE64 wiki page.
