N2 - A capacitor-less LDO with fast response achieving - 88dB PSR at 10kHz in 0.18μm BCD process is proposed. A Frequency Compensation and Fast Transient response Enhancement Circuit (FC&FTEC) and a Negative Capacitance Circuit (NCC) are applied, in order to enhance the PSR and response. The post simulation results show that the LDO achieves -88 dB PSR at 10kHz. When the load current changes from 300 μA to 50 mA or from 50mA to 300uA, the rise time and the fall time are 100 ns respectively, the recovery time is less than 2.02 μs, the quiescent current is 126 μA. The undershoot and overshoot are only 98mV and 185mV respectively.
