WebMay 4, 2024 · Buck Converter As was mentioned above, an LDO circuit is best compared to a buck converter as they are both step-down components. The goal of any switching converter is simple: to produce a stable, yet adjustable, output voltage by modulating the current and voltage delivered to a load with a switching element. WebApr 18, 2024 · April 18, 2024 By Jeff Shepard. The power supply rejection ratio (PSRR) describes the ability of a circuit to suppress any power supply variations from passing to its output signal and is typically measured in dB. It’s most often used with operational amplifiers (op amps), dc/dc converters, linear regulators, and low drop out regulators (LDOs).
