NOTES

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

2TCVO is defined as the ratio of output change with temperature variation to the specified temperature range expressed in ppm/ °C.

TCVO = (V max–V min)/VO (TMAX–TMIN).

3Guaranteed by characterization.

4Line and load regulation specifications include the effect of self-heating.

Specifications subject to change without notice.
