Maximum dropout voltage is 0.22 V at the full 50 mA load. That means the input must stay above 4.92 V to maintain regulation — a tight margin if the input is a 5 V rail with tolerance. The PSRR of 63 dB at 1 kHz gives about 0.7 mV ripple rejection per millivolt of input ripple, which is adequate for powering analog front-ends or sensor bias circuits where 1 kHz switching noise from a buck converter needs attenuation. For battery-powered designs drawing a few milliamps total, the 95 µA overhead is noticeable but acceptable for a fixed-output LDO with enable capability. For BOM lines that require this exact fixed 4.7 V output in SOT-23-5, procurement must rely on surplus or broker channels. The regulator includes an enable pin for on/off control, plus built-in protection against over-current, over-temperature, and short-circuit conditions. These features reduce external component count in designs where a simple enable signal from a microcontroller or supervisor IC gates the rail.","metaTitle":"LP2980AIM5-4.7 LDO Regulator, 4.7V Fixed, 50mA, SOT-23-5","metaDescription":"Texas Instruments LP2980AIM5-4.7 LDO voltage regulator, fixed 4.7V 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)":"4.7V"}},"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/LP2980AIM5-4.7/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy LP2980AIM5-4.7?","answer":"The LP2980AIM5-4.7 is obsolete and no longer in production.
