TPS7A8300: alternative device

Part Number: TPS7A8300
Other Parts Discussed in Thread: TPS7A7200, TPS7A89, TPS7A85, TPS7A85A, TPS7A54, UC285, UC385

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
