LP3925: PSRR graph of LP3925 between 1KHz to 10MHz

Part Number: LP3925

Hi,

I am planning to use LP3925 in one of my designs. I am planning to use buck regulators on LP3925 and then provide its output as input to the LDO. From datasheet I understand that switching frequency of buck regulators is around 2.5MHz - 3MHz. It is essential for me reject this switching frequency for my further stages. But the PSRR data is given at 10KHz only. I would like to know PSRR value over frequency range of 10KHz to 10MHz. This is important for my design. Hence I request you to provide PSRR graphs for various LDOs upto 10MHz.

Thanks & Regards,

Kiran

  • Hi Kiran,

    I have assigned your request to concerned Applications Engineer and we will get back to you as soon as possible. Please note that this is vacation time in US and there may be some delay in answering your question.

  • Kiran,
    I realize that you have some time reviewing and potentially designing in this IC. The bad news is that this part is not recommended for new designs. At this time TI is not supporting the LP3925.
    We do have many newer IC that would be a great fit for your application. Please contact your local FAE to find a proper replacement for this part.

    Sincerely,

    Gordon Varney
