The adjustable output is set by an external resistor divider from a 1.24 V reference, giving flexibility to dial in any output between 1.24 V and 29 V. ## Dropout and headroom — what the numbers mean The maximum dropout voltage is 0.6 V at 100 mA load. That means the input rail must stay at least 0.6 V above the programmed output to maintain regulation. For a 5 V output, the input needs at least 5.6 V — and that's at full load. At lighter loads dropout drops lower, but the worst-case number is the one to design around for margin. Input voltage can go up to 30 V, so the LP2950CN can sit on an unregulated 24 V industrial rail or a 12 V battery bus with plenty of headroom for load-dump transients. The 120 µA quiescent current keeps the idle draw low enough for always-on supplies in battery-backed equipment. ## Through-hole packaging and protection The wide pin spacing makes hand-prototyping and field repairs straightforward. On-chip protection includes over-current, over-temperature, and short-circuit shutdown, so the regulator doesn't self-destruct when the output gets a hard fault. ## Obsolete — plan the BOM transition The 8-DIP footprint is common across many adjustable LDOs, but a drop-in replacement is not guaranteed without validating the pinout and compensation.","metaTitle":"LP2950CN Adjustable LDO Regulator, 100 mA, -40°C to 125°C","metaDescription":"Texas Instruments LP2950CN positive adjustable LDO voltage regulator. 100 mA output, 0.6 V dropout, 30 V input max, -40°C to 125°C. 8-DIP through-hole.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","PSRR":"-","Series":"-","Package":"Tube","Output Type":"Adjustable","Mounting Type":"Through Hole","Package / Case":"8-DIP (0.300\\\", 7.62mm)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Control Features":"-","Current - Output":"100mA","Base Product Number":"LP2950","Protection Features":"Over Current, Over Temperature, Short Circuit","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)":"29V","Supplier Device Package":"8-PDIP","Current - Quiescent (Iq)":"120 µA","Voltage - Output (Min/Fixed)":"1.24V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3b58f7b03bf3bf4df49830b1845711da.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LP2950CN/alternatives.json"},"ai":{"faq":[{"question":"Is the LP2950CN obsolete?","answer":"Yes, the LP2950CN is marked as obsolete by Texas Instruments.
