The divider (resistors R1 and R2 ) from VREF makes the reference voltage, which will be provided to the noninverted input of the error amplifier, less than output voltage. In the fixed voltage source where the output voltage will be fed back to the error amplifier directly as shown in figure 1. Output voltage will be divided VREF since the output voltage is equal to the reference voltage. Thus, the output voltage VOUT is: VOUT = nVREF, n = R2 R1 + R2 VIN VCC VC VREF VOUT R1 2.15kΩ CREF 1µF R2 4.99kΩ CL RSC = 0 VOUT CS VIN(+) VIN(–) VEE R3 1.5kΩ C1 COMP 100pF Figure 1 Low Voltage (2 to 7 V) Regulator High Voltage (7 to 37 V) Regulator: Figure 2 shows the construction of a regulator whose output voltage is higher than the reference voltage, VREF. VREF is added to the non-inverted input of the error amplifier via a resistor, R3. The feedback voltage is produced by dividing the output voltage with resistors R1 and R2. Thus, the output voltage VOUT is: VOUT = VREF R2 , n= n R1 + R2 VIN VCC VREF R3 3.8kΩ VIN(+) VEE VC VOUT CL CS VIN(–) COMP RSC = 0 VOUT R1 7.87kΩ R2 C1 100pF 7.15kΩ Figure 2 High Voltage (7 to 37 V) Regulator 5 HA17723/F/P 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, –VOUT, increases in the negative direction. As the voltage across the R 1 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. The output voltage –VOUT of this circuit is: R1 + R2 R3 × V R3 + R4 R1 REF (R1 + R2) · (R3 + R4) R3 =– V × R2 · (R3 + R4) – R4 · (R1 + R2) R3 + R4 REF –VOUT = – R2 11.5kΩ VCC VIN VC VREF VOUT R5 2kΩ Q VZ R4 3kΩ CL CS VIN(+) VIN(–) R3 R1 3kΩ 3.65kΩ C1 COMP 100pF VEE VOUT Figure 3 Negative Voltage Regulator How to Increase the Output Current: To increase the output current, you must increase the current capacity of the control circuit.

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.

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. The output voltage VOUT in the circuit in figure 10 VOUT = R1 + R2 R4 × – 1 VREF R3 + R4 R1 Figure 11 is the circuit diagram of a negative fixed voltage source in floating type.
