LM4041C12IDCKR: what's the meaning of 100ppm/℃ ? where to check the Temperature Drift for Different Average Temperature Coefficients on 100ppm/℃ ?

why reference voltage is so big offset from figure 1? but from figure 5, reference voltage offset drift is small, how to understand it?

thanks.

Hi Max,

From looking at this old datasheet, it seems that this is a typo. This graph is suppose to have Reference Voltage (%) and not Reference Voltage (V).
This graph is suppose to be similar to the graph on the LM4140-N datasheet.
This is correct on the LM4140-N variant of the device.

I would recommend to use the LM4041-N because it has more voltage options and variants that you can use.
