That matters when the 1.8V rail feeds an analog front-end, an ADC reference, or a PLL supply — places where switching noise couples into the signal path. The 95 µA quiescent current keeps the overhead low for battery-powered designs. The regulator includes an enable pin for on/off control, plus over-current, over-temperature, and short-circuit protection — standard safeguards for a 50mA LDO that might see a momentary load fault or a hot environment. The maximum dropout voltage is 0.22V at full load, so the input rail can sit as low as 2.02V and still hold regulation.","metaTitle":"LP2980IM5X-1.8/NOPB LDO Regulator, 1.8V Fixed, 50mA","metaDescription":"Texas Instruments LP2980IM5X-1.8/NOPB LDO voltage regulator, fixed 1.8V output, 50mA, 63dB PSRR at 1kHz, SOT-23-5.","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)","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)":"1.8V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/865be670b7e185d590e6565808fed4d6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LP2980IM5X-1.8%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"What package is LP2980IM5X-1.8/NOPB in?","answer":"It comes in a SOT-23-5 package (also referred to as SC-74A, SOT-753).
