摘要：
A transient-improved output-capacitor-less low dropout (LDO) regulator based on single Miller capacitor feedforward compensation (SMFFC) is presented in this paper. With the SMFFC, the slew-rate at the gate of power transistor is enhanced, which results in an improved transient response during a fast load current transient. The die area of the LDO implemented in 130nm CMOS process is only 0.0113mm(2). Experimental results show that the developed LDO is stable for C-L=OpF within 0-50mA full load range. Besides, the output voltage of LDO can recover within 190ns with less than 75mV voltage spike when the load current changes from lmA to 50mA.
