7. T_low = 0°C for MC78XXAC, C T_high = +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 V_O due to heating effects must be taken into account
separately. Pulse testing with low duty cycle is used.
