Abstract
An output-capacitor-free adaptively biased low-dropout regulator with transient enhancement (ABTE LDR) is proposed. Techniques of Q-reduction compensation, adaptive biasing, and transient enhancement achieve low-voltage high-precision regulation with low quiescent current consumption while significantly improving the line and load transient responses and power supply rejections. The features of the ABTE LDR are experimentally verified by a 0.35-μm CMOS prototype.
