Its PSRR holds at 60 dB from 10 kHz to 100 kHz — the band where most downstream switching regulators produce their ripple — so this LDO cleans the rail for noise-sensitive analog loads like ADC front-ends or PLL supplies without needing a post-filter. ## Dropout, quiescent draw, and thermal envelope Maximum dropout is 0.15 V at the full 300 mA load, meaning the input-to-output headroom must stay above 150 mV across the load range to keep regulation. Quiescent current is 105 µA typical, with a maximum supply draw of 240 µA — low enough for always-on rails in battery-powered equipment. ## TSOT-23-5 package and board integration Supplied in the TSOT-23-5 package (SOT-23-5 Thin variant), surface-mount. The part is available in Tape & Reel (TR) or Cut Tape (CT) options for prototyping or production runs.","metaTitle":"ADP122AUJZ-2.7-R7 LDO Regulator, 300mA, 2.7V Fixed","metaDescription":"Analog Devices ADP122AUJZ-2.7-R7 LDO, 2.7V fixed output, 300mA, 60dB PSRR, TSOT-23-5.

All other ratings — 300 mA output current, 60 dB PSRR, TSOT-23-5 package, protection features — are identical. The choice is driven by the target rail voltage required by the downstream load."},{"question":"What is the PSRR of ADP122AUJZ-2.7-R7 and why does it matter?","answer":"The PSRR is 60 dB across 10 kHz to 100 kHz. This is the frequency range where switching regulators generate their fundamental ripple and harmonics. A 60 dB rejection means the output ripple from a 10 mVpp switching spike is attenuated to roughly 10 µVpp — clean enough for precision analog circuits like data converters or sensor front-ends."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/ADP122AUJZ-2.7-R7","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/ADP122AUJZ-2.7-R7 when reusing this data.
