Hi, LDO support team

Our customer ask me about the value of the internal divided resister(Rupper and Rbottom) in TPS70925.

Please let me know about two resister value.

Regards,

Tamio

Hi Tamio,

Please allow a day or two for us to lookup this information. Please keep in mind that the ratio is trimmed and ensured at final test rather than the exact resistance value.

Very Respectfully,
Ryan

Hi Tamio,

The internal reference is 1.2 V and the internal R2 is nominally 11 MΩ. As a result R1 is approximately 12 MΩ for the 2.5 V version of TPS709. Please keep in mind that the ratio is trimmed and ensured at final test rather than the exact resistance value.

Very Respectfully,
Ryan
