3.0 V mode typically adds 100 µA to the quiescent current. Also, I
The long-term stability specification is noncumulative. The drift in subsequent 1,000 hour periods is significantly lower than in the first 1,000 hour period.
The operating temperature range is defined as the temperature extremes at which the device will still function. Parts may deviate from their specified performance
Maximum output voltage drift is guaranteed for all packages.
