The 0.22 V max dropout at 50 mA means the input can sit as low as 3.12 V and still hold regulation. For a 3.3 V bus with a 0.4 V drop budget, that works; below that, the headroom vanishes. Quiescent current is 95 µA typical. That is not the lowest in the 50 mA class, but it keeps the always-on draw manageable for battery-powered equipment that does not spend most of its time in deep sleep. Housed in a SOT-23-5 (SC-74A) package, surface-mount, with an Enable pin for on/off control.","metaTitle":"LP2980IM5-2.9/NOPB LDO Regulator, 2.9V Fixed, 50mA, SOT-23-5","metaDescription":"Texas Instruments LP2980IM5-2.9/NOPB is a 50mA fixed-output LDO with 63dB PSRR at 1kHz, 0.22V dropout max.","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)":"2.9V"}},"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/LP2980IM5-2.9%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"Is LP2980IM5-2.9/NOPB obsolete?","answer":"Yes, Texas Instruments lists the LP2980IM5-2.9/NOPB as Obsolete.
