Part Number: TPS7A91

Hi Team，

Could you help to check the accuracy of the Vref over operating temperature range? From the accuracy spec of Vout, it seems with in -1% ~ 1%. I would like to know is Vref accuracy related to Vin and Iout?

Regards,
Hailiang

    Hi Hailiang, 

    I looked at some Char Data and test data. This is a trim parameter and the deviation is so small that it is listed as a typ. 

    Furthermore, any drift will be seen at the output, therefore, we can look at the Vout accuracy by looking at the Load and Line regulation plots: 

    There is some relationship as observed from the plots and looking at the test conditions. The variation will be a combination of these parameters, but overall, it is highly recommended to use what is listed on the DS since we can guarantee the performance of the device based from the data sheet. 

    Best,
