TPS7A83A: Difference between TPS7A83A and TPS7A8300

Part Number: TPS7A83A
Other Parts Discussed in Thread: TPS7A8300,

Hello,

I want to use the TPS7A83A for new designs, but when I try to order samples it only shows TPS7A8300 parts (which appears to be a different LDO part number). Are they the same? What are the differences? Can I order the TPS7A83A?

    I hope this answers your question.
