Original question:

TPS7A96: regarding Softstart

TPS7A96: output noise density in TPS7A96

Part Number: TPS7A96

Tool/software:

Hi Team,

I want to double check with you about the noise density in TPS7A96, do you have some data in Vout=5.4V with output current 200mA-300mA?

 Thanks.

BRs.

    Hey Frank.

    Thank you for your question. No, we don't have any data for these parameters. I can submit a simulation request if you would like. This can take 2 - 3 weeks/

    Let me know if you have any other questions.

    Thanks,

    Vahnroy

    Hi Vahnroy,

    I am afraid that 2-3weeks is too long since we need to reply to customer before 7/11. The key spec for them on device selection is:

    1. Noise density need to be lower than 2nV/rtHz with VOUT=5.4V @10kHz

    2. Noise density need to be lower than 50nV/rtHz with Vout=5.4V @10Hz

    Do you have any other device to recommend? Thanks.

    BRs.

    Hey Frank,

    This device will definitely be able to meet those specs. You should expect figures slightly lower than what's stated in the datasheet due to the decreased output current in your use case.

    Hope this helps,

    Thanks
