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. WebSep 1, 2024 · The LDO regulator is an important power management module that provides noise-free constant supply voltage to various sub-systems of system-on-chip (SoC). The design of a low power, stable, noise-free cap-less LDO regulator with good voltage regulations and fast transient responses with edge time below is challenging.
