fluctuations in the power supply. This work presents a low dropout regulator that achieves Power Supply Rejection (PSR) better than -40dB over the entire frequency spectrum. ... gain provides high supply ripple rejection at low frequencies, while the output capacitor shunts any ripple appearing at the output to ground at very high frequencies ...
