Chopper-type regulator circuit and chopper-type regulator IC |
摘要 |
A chopper-type regulator circuit includes an output transistor composed of a PNP-type transistor, and a control section for controlling switching of the output transistor based upon a voltage difference between a reference voltage and an output voltage. The control section is provided with a base current output terminal for supplying a base current of the output transistor to a load connected to the chopper-type regulator circuit. This makes it possible to reduce a loss of the circuit, thereby improving efficiency of the circuit.
