LM2596: Tolerance

Danilo A.

Part Number: LM2596

Hi Team,

The datasheet of LM2596 says the output voltage tolerance is 4%. A customer would like to know if there is a standard tolerance and how do you guarantee that its tolerance value is 4%?

Regards,

Danilo

Hi Danilo,

the 4% tolerance is for Tj=25C only, please use 5% for Tj over -40C and 125C operation range. this spec. is guaranteed product validation.

Hi Andy,

Thank you for your quick response. The customer would like to know if there is a standard tolerance value for the output voltage of a regulator or the tolerance value is solely dependent on the requirement of the load?

Regards,

Danilo

Hi Danilo,

Sorry it's hard to find out the standard deviation value for LM2596 FB as it's too old part.

On data sheet Fig1, you can find that the measured output tolerance is far smaller than 4%, we normally specify the min/max tolerance with 6 sigma to cover corner condition.
