The 0.6 V dropout at 100 mA means the input need only sit 0.6 V above the 3.0 V output at full load — useful when the input rail is already close to the output, such as a 3.6 V or 3.8 V supply. Quiescent current is 120 µA typical, keeping the overhead low for always-on or battery-backed domains. The LP2950CZ-3.0/LFT3 carries an obsolete product status. If the design can tolerate a package change, the LP2950 family includes SOT-23 and SOIC-8 variants with the same 3.0 V fixed output and 100 mA rating — but those are not pin-compatible with the TO-92 footprint. A board respin would be required. ## Over-current and over-temperature — built-in, no external parts needed Internal protection circuits guard against over-current and over-temperature events. The regulator folds back or shuts down before the die exceeds safe limits — no need for a series fuse or a separate thermal sensor on the board. For a 100 mA rail powering a sensor or a low-power MCU, this saves two to three BOM lines. ## TO-92 package — the three-lead through-hole footprint The LP2950CZ-3.0/LFT3 comes in a TO-226-3 / TO-92-3 (TO-226AA) through-hole package, supplier device package TO-92-3. It is a three-lead transistor-style outline — input, ground, output — that hand-solders easily and fits into sockets or perfboard. The Bulk shipping form means it arrives loose in an antistatic bag, not taped and reeled; factor that into pick-and-place planning if the line is automated.","metaTitle":"LP2950CZ-3.0/LFT3 LDO Regulator, 3.0V Fixed Output, 100 mA","metaDescription":"LP2950CZ-3.0/LFT3 positive fixed 3.0V LDO regulator, 100 mA output, 0.6V dropout at full load, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","PSRR":"-","Series":"-","Package":"Bulk","Output Type":"Fixed","Mounting Type":"Through Hole","Package / Case":"TO-226-3, TO-92-3 (TO-226AA)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Control Features":"-","Current - Output":"100mA","Base Product Number":"LP2950","Protection Features":"Over Current, Over Temperature","Number of Regulators":"1","Output Configuration":"Positive","Operating Temperature":"-40°C~125°C","Voltage - Input (Max)":"30V","Voltage Dropout (Max)":"0.6V @ 100mA","Current - Supply (Max)":"14 mA","Voltage - Output (Max)":"-","Supplier Device Package":"TO-92-3","Current - Quiescent (Iq)":"120 µA","Voltage - Output (Min/Fixed)":"3V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/065dec4a1ee9af3359aa2dd6a16fc1f7.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LP2950CZ-3.0%2FLFT3/alternatives.json"},"ai":{"faq":[{"question":"Is LP2950CZ-3.0/LFT3 obsolete?","answer":"Yes, the LP2950CZ-3.0/LFT3 is listed as obsolete.
