Can someone help with part TPSM861253 in QFN-FCMOD package

[boddeke]

this seems like a great part. i want to use it to power 3.3v remote smart-sensors of 12v. can someone help? has a similar part? this goes beyond my fritzing design skills! thanks, frank

I don’t think this part can be made in Fritzing. It appears to want a custom solder mask which is independent of the copper and Fritizing (AFAIK) doesn’t support that.

The green internal line appears to be the solder mask and copper is supposed (I think!) to extend beyond that. Fritzing will unmask all the copper on the connection automatically so I don’t think this can be done.
