A linear regulator is described that includes a mode selection circuit. In one implementation, the mode selection circuit is operable to receive an input voltage and to set an operation mode to one of a first mode or a second mode (e.g., based on a voltage level of the input voltage) so as to generate an output voltage. For example, when the voltage level of the input voltage is within a voltage range, the mode selection circuit can set the first mode as the operation mode to supply the input voltage as the output voltage to a load without voltage regulation. Similarly, when the voltage level of the input voltage is outside the voltage range, the mode selection circuit can set the second mode as the operation mode to regulate the output voltage to the load.
