PSRR of low dropout voltage regulators

Here’s an app note about PSRR of LDO from Microchip. The Power Supply Rejection Ratio is the ability of a device, such as a Low Dropout Voltage regulator, to reject the various perturbations that can be found in its input supply rail by providing a greatly attenuated signal at the...

Connecting LDOs in parallel

App note from ROHM semiconductor on combining LDOs for higher load capacity. When you want to increase the output current capacity of an LDO, or when the power dissipation of a single LDO is insufficient, you might think of connecting LDOs in parallel if you need to disperse the...
