Abstract:
To provide a voltage regulator capable of switching a voltage of an output terminal from an internal voltage to an external voltage while suppressing an increase in circuit scale. The voltage regulator includes a voltage output circuit configured to generate a constant internal voltage lower than an external voltage applied to an input terminal from the external voltage and supplying the constant internal voltage to an output terminal, a temperature sensing circuit configured to decrease an output voltage of an output node thereof according to a rise in temperature, an overheat detection circuit connected to the output node of the temperature sensing circuit and a test terminal, and a voltage detection circuit connected to the output node of the temperature sensing circuit and the test terminal.

Claim (Index 9):
The voltage regulator according to  claim 1 , wherein\n the voltage output circuit comprises: an error amplifier configured to receive a voltage based on a voltage of a voltage adjustment terminal provided separately from the output terminal and a reference voltage, an output transistor having a source connected to the input terminal, a drain connected to the output terminal, and a gate configured to be controlled based on a voltage supplied from the error amplifier, a PMOS transistor having a gate configured to receive the output stop signal, a source connected to the input terminal, and a drain connected to the gate of the output transistor, and a clamp circuit and a switch connected in series between the input terminal and the gate of the output transistor, the clamp circuit configured to clamp a voltage of the gate of the output transistor so that the voltage of the gate of the output transistor does not fall below a prescribed voltage when the switch is on state, the switch is configured to turn off according to receiving of the test mode signal, and the voltage adjustment terminal is configured to receive a voltage lower than the internal voltage when the voltage detection circuit outputs the test mode signal.
