LDOs are Low Drop-Out Linear regulators. But what exactly does Low Dropout mean? How well does an LDO regulate the output voltage when the input voltage is very close to the output voltage? Our tutorial video will explain the LDO dropout operation and dropout curves, and gives a practical measurement example of the RT9187 LDO cl...

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 f...

To get the most out of your LDO application, the LDO power dissipation needs to be carefully considered. The power dissipation in the LDO is determined by the voltage drop across the LDO multiplied by the current passing through the LDO. Increasing the LDO voltage drop or the LDO current quickly leads to higher dissipation. But ...
