WebSep 1, 2011 · The PSR of the proposed LDO is −46 dB at 1 KHz and −2.5 dB at 1.1 MHz. The PSR degrades at −20 dB/decade from ω dominant (about 5 kHz) and remains flat after ω ugb (about 1.1 MHz), which... WebAbstract—A low drop-out (LDO) regulator with a feed-forward ripple cancellation (FFRC) technique is proposed in this paper.The FFRC-LDO achieves a high power-supply rejection (PSR) over a wide frequency range.Complete analysis and design steps of the FFRC-LDO are presented in this paper. Kelvin connection is also used to increase the gain–bandwidth of …

The load and line regulations were 0.089 μV/mA and 0.81 mV/V, respectively. Figure 9 depicts the PSR of the LDO under different load currents when V I N = 1.6 V and V o = 1.2 V. The PSR benefitted from the high loop gain and the current-mirror load structure used in the driving stage.
