| Abstract: | A low-dropout regulator for on-chip application with active feedback and a slew-rate enhancement circuit to minimize compensation capacitance and speed up transient response is presented in this brief. The idea has been modeled and experimentally verified in a standard 0.35-μm CMOS process. The total compensation capacitance is 7 pF. From experimental results, the implemented regulator can operate from a supply voltage of 1.8–4.5 V with a minimum dropout voltage of 0.2 V at a maximum 100-mA load and IQ of 20 μA. |
