Recommendations on inverting LDO that has EVM with 24V or 5V input & -5V output?

Hi,

Do you have any recommendations on an inverting LDO that has EVM with 24V or 5V input & -5V output? It seems the TPS67 series doesn't has an EVM anymore.

    HI Sebestian,

    Unfortunately we do not have an LDO that can take a positive voltage and make a negative rail. Depending on your load current requirement, we have a number of DC/DC converters or charge pumps that can do this.  Whatever works best for you to create the negative rail, the TPS723 can clean up and help produce a low noise output.

    I hope this helps.

    Regards,
