1

For proper operation, a 1 µF capacitor is required between the OUTPUT pin and the GND pin of the device.

2

TCVOUT is defined as the ratio of output change with temperature variation to the specified temperature range expressed in ppm/°C.

TCVOUT = (VMAX

− VMIN)/VOUT(TMAX − TMIN)

3

Load regulation specification includes the effect of self-heating.
