Notes:

1) The specified values are without external trim.

2) The temperature coefficient is determined by the

box method. See discussion on temperature

performance.

3) Line and load regulation are measured with pulses and

do not include voltage changes due to temperature.

4) Hysterisis over the operating temperature range.
