WebThis effectively reduces the PSRR between the old and new 0dB crossover points. If improving the PSRR at a high frequency and reducing overall output noise are not critical, the common practice is to decrease the output capacitance in order to improve the PSRR (Figure 3). The same conclusion is applicable to the N-channel FET regulator (Figure 3). WebNov 20, 2014 · Abstract: This paper provides a detailed analysis of the power-supply rejection ratio (PSRR) of low-dropout (LDO) regulator. The paper includes circuit modeling of a generic LDO with signal injection at its supply. Based on the modeling, the transfer function of PSRR is derived.
