A low-dropout regulator with a single-transistor-control providing improved transient response and stability is dis closed. The single-transistor-control provides a dynamic resistance at the output of the regulator for minimizing undershoot and overshoot, and hence improves transient response. Since the single-control transistor reduces the output resistance of the regulator, the output pole is pushed to a suf? ciently high frequency without a? cecting stability. Therefore, the limited choice of combinations of the output capacitance and its equivalent-series-resistance is substan tially relaxed.
