TPS7A91: MIn/Max of VREF and Rdis

Hirotsugu Kobayashi

Part Number: TPS7A91

Hi, team.

Please tell me the minimum and maximum of Vref (=0.8V).

I think that VOUT accuracy is included Vref tolerance and Line/Load regulation, but I'd like to know the tolerance of VREF only.

Also, please tell me the minimum and maximum of Rdis.

Datasheet is described typical 250-ohm only.

Hi Hirotsugu,

Unfortunately this is information is not readily available, but as this is an adjustable device the reference is going to contribute the largest error in the device. The Vref accuracy will be really close to the overall accuracy of the device (+/- 1%).

Regards,
Mark
