Its headline spec is the PSRR curve: 85 dB at 100 Hz rolling off to 50 dB at 10 MHz — that bandwidth covers switching-regulator ripple and its harmonics, not just the fundamental. Rated for 200 mA output with a maximum dropout of 100 mV at full load, the headroom between input rail and the 1.2 V fixed output needs to stay above that 100 mV across load and temperature to keep regulation. ## Industrial temperature grade and enable control Operating from -40°C to 125°C, this LDO suits engine-bay or outdoor enclosure deployment where the ambient temperature pushes past the commercial 85°C ceiling. The enable pin lets a system sequencer or supervisor gate the output — useful in multi-rail power-up schemes where the 1.2 V rail must not rise before the core supply. Quiescent current is 250 µA typical; the 200 mA output is internally current-limited and thermally protected, so a sustained overload or short on the output shuts the part down rather than exceeding the junction temperature.","metaTitle":"MIC94310-4YM5-TR Ripple Blocker™ LDO, 200mA, 85dB PSRR","metaDescription":"Microchip MIC94310-4YM5-TR Ripple Blocker™ LDO, 1.2V fixed output, 200mA, 85dB~50dB PSRR (100Hz~10MHz), SOT-23-5, active production, ROHS3 compliant.","metaKeywords":null},"attributes":{"series":"Ripple Blocker™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"PSRR":"85dB ~ 50dB (100Hz ~ 10MHz)","Series":"Ripple Blocker™","Package":"Tape & Reel (TR); Cut Tape (CT)","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"SC-74A, SOT-753","lifecycle_stage":"eol_hot","Control Features":"Enable","Current - Output":"200mA","Protection Features":"Over Current, Over Temperature","Number of Regulators":"1","Output Configuration":"Positive","Operating Temperature":"-40°C ~ 125°C","Voltage - Input (Max)":"3.6V","Voltage Dropout (Max)":"0.1V @ 200mA","Supplier Device Package":"SOT-23-5","Current - Quiescent (Iq)":"250 µA","Voltage - Output (Min/Fixed)":"1.2V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.31","priceTiers":[{"qty":1,"price":"$0.31000","currency":"USD"},{"qty":25,"price":"$0.25520","currency":"USD"},{"qty":3000,"price":"$0.25500","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/0295912df5ca2054c262ae3f7844c0df.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MIC94310-4YM5-TR/alternatives.json"},"ai":{"faq":[{"question":"What is the PSRR of MIC94310-4YM5-TR?","answer":"PSRR is 85 dB at 100 Hz, rolling to 50 dB at 10 MHz.
