摘要：
A power supply (10) apparatus generates an output voltage. Boost means (700) boosts a voltage supplied from a reference voltage source and generates a first power supply voltage. Processing means (300) controls switching the boost means on and off. A first transistor (Tr1) is connected to the first power supply voltage. A second transistor (Tr2) is connected to a collector of the first transistor. A resistance element (R0) is connected to a collector of the second transistor. A voltage source (VPR) is connected to the resistance element and generates a second power supply voltage. A collector voltage, which is an output voltage, of the second transistor is controlled by controlling an amount of base current of the first transistor.
