High bandwidth regulators

WebThis paper presents a novel capacitor-less low-dropout regulator (LDO) for mobile applications. The proposed capacitor-less LDO utilizes multiple feedback loops to satisfy several design challenges for some mobile applications which were not considered in the previous capacitor-less LDOs. The proposed LDO has a wide bandwidth of 3.03 MHz at … Web16 de jun. de 2015 · Most LDOs have comparatively high PSRR at lower frequencies normally 10 Hz – 1 kHz. The LDO having high PSRR over a wide band can reject very high frequency noise same like noise arising from a switcher. PSRR fluctuates over some parameters like frequency, temperature, current, output voltage, and the voltage differential.

Output Voltage Noise Measurements for Linear Regulators

WebLinear regulators have very low output voltage ripple because there are no elements switching on and off frequently and linear regulators can have very high bandwidth. So there is little EMI problem. Some special LDOs, such as Analog Devices LT1761 LDO family, have as low as 20μV RMS noise voltage on the output.
