摘要： There is provided a low drop-out regulator. The low drop-out regulator includes an amplifier including an odd number of operational amplifiers connected to one another in series, and an output unit including a pass transistor operated by an output from the amplifier and generating an output voltage to be applied to a load, wherein the pass transistor is an N-channel transistor, and the amplifier controls a feedback loop gain between an output terminal of one of the odd number of operational amplifiers and the output unit. The feedback loop gain may be controlled independently from the trans-conductance of the pass transistor, whereby the stable output voltage may be generated, even in the case that the load and the input voltage are changed, and the design parameter may be simplified.
