Hi team,
Due to the constrained supply of TPS7A8300, we recommended TPS7A8400. However, its supply is still tight. From this thread, TPS7A7200 can be a choice. Besides this, I also recommended to use TPS7A89 to replace 2 TPS7A8400.
Except for these 2 points, could you please provide some other suggestions and comments to replace TPS7A8300?
Besides, do you have alternative device suggestions for TPS7A8500?( Except TPS7A8400)
Thanks!
Thanks & best regards,
Wendy
