1 For proper operation, a 1 μF capacitor is required between the output pin and the GND pin of the device.
2 TCVO is defined as the ratio of output change with temperature variation to the specified temperature range expressed in ppm/°C.
TCVO = (VMAX
− VMIN)/VO(TMAX − TMIN)
3 Guaranteed by characterization.
4 Line and load regulation specifications include the effect of self-heating.
