Hi, support team


Could TPS73501DRB be a direct replacement for the TPS73701DRBR part without changing any hardware?

But I could see in the datasheet of TPS73501DRB where mentioned that Cff is required.
Will it make harmfully affect if using part TPS73501DRB without providing Cff?.

If it make harmfully affect, could you help to find other substitute of TPS73701DRBR without changing any hardware?

Thanks so much.

Best regards,
Yuki

    Hello,

             TPS73501DRB requires CFF for the device to remain stable. If CFF cannot be accommodated, then it it cannot be a direct replacement for TPS737. TPS732 is an output adjustable LDO that comes in a 8 pin DRB package and doesn't require CFF for stability. Depending on other requirements, it could potentially be a replacement for TPS73701DRB. Thanks!
