For proper operation, a 1 μF capacitor is required between the output pin and the GND pin of the device.
TCV O is defined as the ratio of output change with temperature variation to the specified temperature range expressed in ppm/°C.
TCV O = ( V MAX ? V MIN )/ V O ( T MAX ? T MIN )
Guaranteed by characterization.
Line and load regulation specifications include the effect of self-heating.
