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. WebOct 25, 2024 · In an ideal world, and without any output capacitor, the gain reduces until it is equal to one. This point is called the transition frequency. In the real world, an LDO needs some output capacitor to be stable. Its impedance together with the parasitic impedance form an filter which helps to improve the high-frequency PSRR characteristic. Figure 1.
