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...

LDO regulator boasts high PSRR
by Susan Nordyk @ edn.com: In addition to low noise, the LT3045 linear regulator from Linear Technology provides a PSRR (power supply rejection ratio) of >90 dB to 10 kHz and >70 dB to 2.5 MHz, quieting noisy or high-ripple input supplies. The LDO regulator’s ultralow spot...

Bias generators with ultralow noise and ripple for sensitive circuits
The LT®3095 generates two low-noise bias supplies from a common input voltage ranging from 3V to 20V. Each channel includes a fixed frequency, peak current-mode step-up switching regulator and a low-noise, singleresistor- programmable 50mA linear regulator. The linear regulator’s...
