Initial accuracy does not include shift due to solder heat effect (see the Applications Information section).
Line and load regulation specifications include the effect of self-heating.
Long-term stability specification is noncumulative. The drift in subsequent 1000-hour periods is significantly lower than in the first 1000-hour period.
For proper operation, a 1 μF capacitor is required between the output pin and the GND pin of the device.
TCV
Guaranteed by characterization.
Line and load regulation specifications include the effect of self-heating.
