WebAdding droop in a voltage regulation circuit increases the headroom for load transients. All electrical systems have some amount of resistance between the regulator output and the load. At high currents, even a small resistance results in substantial voltage drop between the regulator and the load. Conversely, when the output current is (near ... WebAn analog solution of the capacitor-less low dropout regulator (CL-LDO) using the adaptive DC level shift (ADLS) and bulk-driven feed-forward (BDFF) techniques is proposed. The ADLS circuit is adopted to increase the headroom of the pass transistor's gate voltage, which achieves a larger current loading capability without increasing the size of the pass …
