parameter
1. High temperature and mechanical stress can effect the initial accuracy of this reference series.See
2. The temperature coefficient is determined by the box method. See discussion on temperature perfor-
3. The minimum input to output differential voltage at which the output voltage drops by 0.5% from
4. Based on 1.024 V output. Noise is linearly proportional to V
5. Defined as change in 25ºC output voltage after cycling device over operating temperature range.
6. Line and load regulation are measured with pulses and do not include output voltage changes due to
discussion on output accuracy.
