Figure 6 Fixed Voltage Source in Shunt Regulator
Switching Regulator
Figure 7 shows a switching regulator circuit. The error amplifier, control circuit, and forward feedback
circuit R
4 and R3 operate in together as a comparator, and make the external transistors Q1 and Q 2 to turn
on/off. In this circuit, the self-oscillation stabilizes the output voltage and the change in output is absorbed
by the changes of the switches conducting period.
Figures 8 and 9 show a negative voltage switching regulator circuit and its characteristics.
