LT8653S Reference Voltage Accuracy (At Room Temperature)


I am considering the LT8653S.

In that, I have a question.


I think this IC can choose 3 kinds of reference voltage (1.8V, 3.3V, 5V).

For the three reference voltages,
Could you tell me the error range at room temperature?

There is a description in datasheet about each error in the whole temperature.
The calculated value is about ± 1.5%.

I am currently developing a medical device.
If this error is not within ± 1%, it will be difficult to adopt.

The operating temperature of the medical device is 10 ° C to 30 ° C.

The reference voltage of 0.8V is
The error at room temperature can be read as about ± 0.75%.
If other 1.8V, 3.3V, 5V have similar error(±0.75%),
As mentioned above, it can be examined because it is a temperature environment of 10 ° C to 30 ° C.

Best regards,
