The 0.6 V maximum dropout at full load means the input rail must stay above 5.6 V to maintain regulation — a 5 V rail from a 6 V battery or a 7.5 V intermediate bus works; a 5.2 V rail does not. ## Dropout and quiescent current — the headroom trade Quiescent current is 120 µA typical, rising to 14 mA max under heavy load or over-temperature. That Iq floor is low enough for always-on rails in industrial sensors or microcontrollers, but the 14 mA ceiling means the thermal budget at 100 mA output includes the dropout power plus the supply current — roughly 0.6 V × 100 mA + 30 V × 14 mA = 480 mW worst-case, which the TO-92-3 package can handle with adequate copper on the leads. For new designs, a pin-compatible replacement should be evaluated — the LP2950 family includes active TO-92-3 variants with the same 5 V fixed output and 100 mA rating. ## Through-hole TO-92-3 — board integration The TO-92-3 (TO-226AA) through-hole package is a 3-lead inline plastic case, 0.100-inch pitch. It is intended for PCB mounting with the leads soldered or socketed.","metaTitle":"LP2950CZ-5.0/LFT8 LDO Regulator, 5V Fixed, 100 mA, TO-92-3","metaDescription":"LP2950CZ-5.0/LFT8 is a 5V fixed-output LDO regulator rated 100 mA, 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":"-","Packaging":"Bulk","Output Type":"Fixed","Part Status":"Obsolete","Mounting Type":"Through Hole","Package / Case":"TO-226-3, TO-92-3 (TO-226AA)","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)":"5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.2700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/065dec4a1ee9af3359aa2dd6a16fc1f7.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LP2950CZ-5.0%2FLFT8/alternatives.json"},"ai":{"faq":[{"question":"What is the output current of LP2950CZ-5.0/LFT8?","answer":"The LP2950CZ-5.0/LFT8 is rated for 100 mA output current.
