It does not depend on the variation between devices due to manufacturing processes. The temperature coefficient range from minimum to maximum is thus not caused by solid-state variations, but by the temperature. The temperature vs. output voltage characteristic is not linear. The temperature coefficient is small at low temperatures (gentle gradient) and increases as the temperature gets higher (steep gradient). The temperature vs. output voltage characteristic curve shape is roughly fixed, however, the characteristic does change slightly due to the temperature accuracy of the device. The SM6610AH/BH have an accuracy of ± 5°C, and the SM6610LH/MH have an accuracy of ± 3°C. The curve for the SM6610AH is shown below. VOUT [V] Tc max.
