C-MOS-Verstärker/Begrenzer (CMOS-Inverter als Verstärker)

The designer of a heavy-duty, variable- voltage, regulated power supply unit always meets the problem of having to allow for the very high dissipation that can occur in the series regulator transis- to_r. When a high output current is drawn at low voltage (TTL!) it may even be necessary to use a cooling fan at the heatsink.
