TPS7A39: TPS7A39

Part Number: TPS7A39

I am looking for a circuit for testing the PSRR of the above mentioned LDO. I dont have any spectrum analyzer or any other instrument to test PSRR. I am looking for a simple circuit which can generate the signals as per the spec in datasheet for testing PSrR.

Do you have any external circuit which can be used for testing the PSRR of any LDOs as per its datasheet spec.

  • Hi Anuraj,

    We do not have a simple external circuit to measure PSRR for LDOs. If you don't have a network/spectrum analyzer, you could use an oscilloscope and signal generator. See the linked app note:
