摘要
Technologies are generally described for a voltage regulator implemented as an integrated circuit (IC). The voltage regulator may include a power transistor configured to receive and convert an input voltage from a voltage source to an output voltage, and a feedback loop configured to regulate the output voltage in response to a change from a desired level. The feedback loop may include an error amplifier configured to determine and amplify a value difference between the output voltage and a reference output voltage, a voltage divider configured to generate voltage proportional to the output voltage such that a ratio is the value difference, and a first unity gain buffer configured to increase stability of the IC. In some examples, the feedback loop may include a second unity gain buffer and/or an overshoot suppressor circuit configured to reduce an output voltage fluctuation when a current consumed by the load is changed suddenly.
