Abstract
Provided are a low dropout regulator and an electronic device. The low dropout regulator comprises a control unit electrically connected to a second capacitor, the control unit being used for controlling the connection or disconnection between a first electrode plate of the second capacitor and a second end of a power tube. Therefore, when the low dropout regulator is in a standby state, the control unit controls the disconnection between the first electrode plate of the second capacitor and the second end of the power tube, such that the second end of the power tube has a relatively small connection capacitance, so as to ensure the separation of a dominant pole point at a control end of the power tube from a secondary pole point at the second end of the power tube, and thus, the low dropout regulator has a high loop stability when same is in the standby state, thereby improving the performance of the low dropout regulator.
