20. Tlow =0°C for MC78XXAC, C

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

*40°C for MC78XXB, MC78XXAB, NCV7805

21. 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.
