The 0.3 V maximum dropout at 100 mA means the input can sag to 5.3 V before the output drops out of regulation — useful on a 5 V rail fed from a battery or a loosely regulated bus. The 0.3 V dropout at 100 mA sets the minimum input-to-output headroom: a 5 V rail from a 5.3 V source works, but a 5.0 V input does not. The quiescent current is 15 mA typical — not a micropower LDO, but acceptable for always-on analog rails where the load current dominates the power budget. Protection covers over-temperature, reverse polarity, and short circuit, so the part survives a miswired bench or a downstream fault without latching up. ## NRND — plan the last-time-buy window","metaTitle":"LM2931AM-5.0 Fixed 5V LDO, 100mA, 80dB PSRR, NRND","metaDescription":"Texas Instruments LM2931AM-5.0 fixed 5V LDO, 100mA output, 80dB PSRR at 120Hz, 0.3V dropout max.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","PSRR":"80dB (120Hz)","Series":"-","Package":"Tube","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Not For New Designs","lifecycle_stage":"eol_hot","Control Features":"-","Current - Output":"100mA","Base Product Number":"LM2931","Protection Features":"Over Temperature, Reverse Polarity, Short Circuit","Number of Regulators":"1","Output Configuration":"Positive","Operating Temperature":"-40°C~85°C","Voltage - Input (Max)":"26V","Voltage Dropout (Max)":"0.3V @ 100mA","Current - Supply (Max)":"30 mA","Voltage - Output (Max)":"-","Supplier Device Package":"8-SOIC","Current - Quiescent (Iq)":"15 mA","Voltage - Output (Min/Fixed)":"5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.1600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/bc5f9d253d87c0f5bb975d3751d9071d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM2931AM-5.0/alternatives.json"},"ai":{"faq":[{"question":"Does LM2931AM-5.0 have over-temperature protection?","answer":"Yes — the protection features include over-temperature, reverse polarity, and short circuit.
