Summary:A switchable linear regulator. The switchable linear regulator comprises a constant voltage source, a differential amplifier, a pass transistor, a first resistor, a plurality of second resistors and a plurality of switches. The differential amplifier has a first input terminal coupled to the constant voltage source and a second input terminal connected to a first node. The pass transistor has a first terminal controlled by the differential amplifier, a second terminal coupled to a supply voltage, and a third terminal connected to a second node. The first resistor is connected between the first and second nodes. Each second resistor comprises one end connected to the first node. Each switch is coupled between the other end of a corresponding second resistor and the ground.
