Its defining parameter is the PSRR curve: 117 dB at 120 Hz, tapering to 56 dB at 10 MHz — a noise-rejection envelope that spans the full audio band and well into the switching-frequency range. For a sensitive analog front-end or a precision ADC supply rail, that means the regulator itself contributes negligible ripple from the upstream rail. ## Dropout and input headroom — 0.35 V at full load Maximum dropout is 0.35 V at 200 mA (typical), so the input rail must stay at least that margin above the set output voltage across load and temperature. With a 20 V absolute maximum input, the part can regulate down to 0 V (adjustable) up to 15 V max output. ## Control and protection — Enable, Power Good, reverse polarity Control features include a dedicated Enable pin, a Power Good flag, and current limit. Protection covers over-temperature shutdown and reverse polarity — the latter is unusual for a linear regulator and saves an external Schottky if the input rail can swing negative during power sequencing. The part is ROHS3 compliant per the lifecycle record.","metaTitle":"LT3042EDD#PBF Analog Devices LDO, 200mA, 117dB PSRR","metaDescription":"LT3042EDD#PBF active-production LDO from Analog Devices. 200mA output, 117dB~56dB PSRR, 20V input, 10-DFN package.
