Low-noise and low-ripple techniques for a high-efficiency, low-loss-supply without an LDO
2022年 1月 5日
Many noise-sensitive systems use low-dropout regulators (LDOs) to provide low-noise and low-ripple power to sensitive analog circuits. But with growing current demands for these rails, designers are struggling to include LDOs because of their size, power loss, thermal rise and cost. In this topic, we will discuss techniques to reduce ripple with existing switching power supplies, and introduce that also reduces low-frequency noise.
