High psr ldo
WebThis means that the LDO can be used in a System on a Chip (Soc) thanks to the absence of an off-chip capacitor. The simulation shows a PSR ${< -70\text{dB}}$ in the audio band ([20, 20k]Hz), a PSR peak below -10dB and a fast transient response of 148ns. Furthermore, Montecarlo and PVT simulations show the robustness of the circuit. http://www.chinesechip.com/chip/list_5_23_6.html
