LM10504: Unused LDO

Kuramochi Tadahiko

Part Number: LM10504

Hi,

I received the following question from my customer.

What should we do anything (i.e. pin termination, register setting...) when the LDO is not used?

I'm recognizing  the "LDO sleep mode "register.

Best Regards,

Kuramochi

    Kuramochi-san,

    Officially there are no additional configurations if the LDO is unused.

    Since the Sleep programming descriptions emphasize that the LDO Sleep bit must be set last, after the bucks are disabled, and first before the bucks are re-enabled, there is a chance that enabling this bit during operation could affect device performance or the other regulators.

    Best Regards,
