NOTES:
1. The specified values are without external trim.
2. The temperature coefficient is determined by the box method. See discussion on temperature perfor-
mance.
3. Line and load regulation are measured with pulses and do not include voltage changes due to tem-
perature.
4. Hysterisis over the operating temperature range.
