Noise reduction due to high ripple rejection ratio

Ripple Rejection Characteristics (PSRR)

It is also called PSRR (Power Supply Rejection Ratio). The ripple rejection ratio is the ratio of the ripple voltage that appears on the output voltage when the ripple voltage component (noise) is superimposed on the input voltage to the input ripple voltage. The larger this value, the smaller the ripple component that appears in the output. The Toshiba LDO regulator achieves high ripple compressibility over a wide frequency range through ultra-high-speed feedback circuit technology.

Digital/analog core power supplies such as CMOS image sensors, MCUs, and RFs, may cause malfunction or performance degradation due to external noises. Therefore, we need to be able to remove switching noise from DC-DC converters etc. of external power supplies, which are sources of noise. In other words, we need to have a higher ripple rejection ratio. In addition to the low-frequency range from DC to 1 kHz, our LDO regulator has a high ripple removal capability up to a high-frequency range from 100 kHz to several MHz, and can be used as a high-quality power supply with low noise.
