EC25 Hardware Design

Hi all,

We were providing external 1.8V for EC25, we use that 1.8V for Sim detection side.

Now I realize that EC25 provide 1.8V itself.

I want to know that is that 1.8V that EC25 provide enough for SIM card detection, or should we use external regulator. Thanks.

Is there any ideas?

If we will have problem later like detecting SIM card, than we can put a 1.8V external regulator.
