DUAL-MODE REGULATOR CIRCUIT
First Claim
1. A dual-mode regulator circuit, comprising:
- a first output terminal;
a second output terminal;
a switching regulator circuit, coupled to the first output terminal, and comprising a first transistor coupled between the first output terminal and ground;
a linear regulator circuit, coupled to the second output terminal, and comprising a second transistor coupled between the second output terminal and a power source;
a detection circuit, configured to turn on the first transistor in order to connect the first output terminal to ground, turn on the second transistor in order to connect the second output terminal to the power source, then generate a detection signal indicating whether an inductor is connected between the first and second output terminals, and then activate the switching regulator circuit or the linear regulator circuit according to the detection signal.
