A low-dropout (LDO) regulator for wide load current IL is proposed in this paper. The proposed source follower-based DC level shifter relieves the loop gain degradation across a wide range of IL. The proposed technique also enhances stability. The proposed LDO is implemented in the 180-nm CMOS process. The improvement of PSRR is 32 dB at 1 kHz and 300 mA IL. The proposed method enhances the line and load regulations. LDO output VOUT variation is reduced by 47 mV at 300 mA IL. The phase margin increases by 50 degree and 31 degree at 30 mA IL and 300 mA IL, respectively. © 2022 IEEE.
