Hi,
We are considering to use TPS797, or more specifically TPS79733. One of its tasks would then be to act as reference voltage for some ADC measurements. Therefore we would like to ensure that we understand the accuracy details correctly.
1. The datasheet states an output voltage accuracy of +/- 4%. Is the expected behavior that each LDO unit typically ends up at a static offset from 3.3V within this 4% range, so that one could calibrate away the offset once for each board after building? Or could/will the output voltage for an inidividual LDO vary within that range from time to time so that the (unloaded) output voltage one time could be for instance +1% and another time -1%?
2. The load regulation is stated as 5% in amperes. Should the unit volts, or how should the value be interpreted?
Thanks!
