NOTES

1For proper operation, a 1

µF capacitor is required between the output pin and the GND pin of the device.

2TCV

O 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).

3Guaranteed by characterization.

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

Specifications subject to change without notice.

(@ VS = 5.0 V, –40 C

≤ TA ≤ +125 C, unless otherwise noted.)
