7. Tlow =0°C for MC78XXAC, C

Thigh = +125°C for MC78XXAC, C, NCV7805

=

*40°C for MC78XXB, MC78XXAB, NCV7805

8. Load and line regulation are specified at constant junction temperature. Changes in VO due to heating effects must be taken into account

separately. Pulse testing with low duty cycle is used.
