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.
