That means the input rail can sag to 2.72 V and the output still holds 2.5 V within regulation. For a 3.3 V bus feeding this LDO, you have 0.58 V of headroom — plenty for the dropout plus any IR drop across board traces. ## 125°C junction — where this LDO lives That is the full automotive-grade junction range, even though this part carries no AEC-Q100 badge. It will hold regulation in an engine-bay ECU, a hot industrial enclosure, or a sealed outdoor sensor pod. The SOT-23-5 package (SC-74A, SOT-753) is a standard footprint — the thermal pad on the PCB should be generously copper-poured to keep the die temperature below the 125°C ceiling when dissipating the dropout voltage times load current. ## Obsolete — sourcing strategy for a discontinued part No last-time-buy window or official successor is recorded in the lifecycle data. ## Protection features — what is built in The regulator includes over-current, over-temperature, and short-circuit protection. The enable pin allows the output to be shut down externally, dropping the quiescent current to near zero for power-save modes. Output type is fixed — no external resistor divider needed.","metaTitle":"LP2980IM5-2.5 LDO Regulator, 2.5V Fixed, 50mA, SOT-23-5","metaDescription":"LP2980IM5-2.5 is an obsolete 2.5V fixed-output LDO from TI, rated 50mA, 63dB PSRR at 1kHz, -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":"63dB (1kHz)","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"SC-74A, SOT-753","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Control Features":"Enable","Current - Output":"50mA","Base Product Number":"LP2980","Protection Features":"Over Current, Over Temperature, Short Circuit","Number of Regulators":"1","Output Configuration":"Positive","Operating Temperature":"-40°C~125°C","Voltage - Input (Max)":"16V","Voltage Dropout (Max)":"0.22V @ 50mA","Current - Supply (Max)":"1.2 mA","Voltage - Output (Max)":"-","Supplier Device Package":"SOT-23-5","Current - Quiescent (Iq)":"95 µA","Voltage - Output (Min/Fixed)":"2.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.7800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/865be670b7e185d590e6565808fed4d6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LP2980IM5-2.5/alternatives.json"},"ai":{"faq":[{"question":"Is LP2980IM5-2.5 obsolete?","answer":"Yes, Texas Instruments lists the LP2980IM5-2.5 as obsolete.
