Negative Voltage Regulator: Figure 3 shows the construction of a so-called negative voltage regulator,

which generates a negative output voltage with regard to GND. Assume that the output voltage, –V
increases in the negative direction. As the voltage across the R1 is larger than that across the R3, which
provides the reference voltage, the output current of the error amplifier increases. In the control circuit, the
impedance decreases with the increase of input current, which makes the base current of the external
transistor Q approach GND. As a result, the output voltage returns to the established value and output
voltage is stable.

Switching Regulator

Figure 7 shows a switching regulator circuit. The error amplifier, control circuit, and forward feedback
circuit R4 and R3 operate in together as a comparator, and make the external transistors Q1 and Q2 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.

Floating-Type Fixed Voltage Source

Voltage sources of the floating type or boost type are typically employed when high voltage output is
required. Figure 10 shows the circuit of a floating-type fixed voltage source. Considering the stabilization
in this circuit, assume that the output voltage increases. At the input terminal of the error amplifier the non­inverted input will become low compared with the inverted input, and the output current of the error
amplifier decreases. Then, the current from the terminal VZ in the control circuit decreases. As a result the
base current of the external resistor Q1 will decrease and collector current will decrease, controlling
increase of the output voltage.
