First time request / comment: Tech Support has told me that a TINA model does not exist for the LP347 POR ckt and that one of the fine folks here might be of help, or point me in the right direction. My interest is in passing a control voltage thru this…
Hi Vishal,
We have the replacement part in preview right now (LP3470A) with release coming soon. The device you inquired about will be functionally replaced by the LP3470A275DBVR.
This part is a pin-to-pin replacement for the LP3470 while also providing…

Please also see attachment for more detail.
Thanks!
