LDO as Ripple Suppressor HD

If your application requires a supply voltage that is free of ripple and noise, you may want to use an LDO as voltage regulator. But how well can an LDO remove ripple and noise from an input supply rail? This is related to the LDO Power Supply Ripple Rejection (PSRR). Find out about PSRR vs. frequency and practical design tips for using a LDO as a ripple and noise filter in our tutorial video.
