TPS7B82-Q1: Is there a pin to pin device to replace it because of supply shortage

Part Number: TPS7B82-Q1
Other Parts Discussed in Thread: TPS7A61-Q1, TPS7B70-Q1, TPS7B63-Q1, TPS7A65-Q1, TPS7B81-Q1, TPS7A66-Q1

Hi

I would like to ask 2 questions below:

1. TPS7B8233 only supports 3.3V output and TPS7B8250 only supports 5V output right? Or TPS7B8233-Q1 also supports 5V output and TPS7B8250 also supports 3.3V output?

2. Do we have a pin to pin device to TPS7B8250Q1 which must need these requirements:

a. 5V output

b. 200mA output at least;

c. pin to pin with TPS7B8250Q1

  • Hello,

    For Question 2, which package are you looking for? Here are some equivalent devices.

    TPS7B8233 only support 3.3V output option, and TPS7B8250 only supports 5V output option.

  • Hello Zirui,

    There are no other P2P alternatives, unfortunately. TPS7A66-Q1 is similar but only rated to 150mA. TPS7B81-Q1 is pin compatible but only rated to 150mA too.
