Abstract:
A linear voltage regulator circuit includes first and second voltage input terminals to receive a first or second external voltage, a voltage output terminal, a voltage regulator unit, a voltage switch unit, and a voltage detecting unit. The voltage regulator unit selectively receives the first or second external voltage controlled by the voltage switch unit. The voltage detecting unit outputs a first control signal to control the voltage switch unit to output the first external voltage to the voltage regulator unit, in response to an output voltage of the voltage output terminal being less than or equal to a predetermined value. The voltage detecting unit outputs a second control signal to control the voltage switch unit to output the second external voltage to the voltage regulator unit in response to the output voltage being greater than the predetermined value.
