The 0.22V max dropout at 50 mA means a 3.5V input rail is sufficient to maintain regulation — useful in battery-powered designs where the input voltage sags under load. PSRR is 63 dB at 1 kHz, which attenuates a 1 Vpp ripple on the input to roughly 0.7 mVpp at the output. This makes it a candidate for powering the analog front-end or VCO supply in RF and instrumentation chains, where switching-regulator noise would otherwise couple into the signal path. ## Industrial temp grade and protection set Built-in over-current, over-temperature, and short-circuit protection handle the common fault scenarios in those environments without external clamp diodes. Existing production runs can still be sourced through independent distribution, but new BOM entries should evaluate a recommended replacement from the same family or a pin-compatible LDO with similar dropout and PSRR.","metaTitle":"LP2980AIM5-3.3 LDO Regulator, Fixed 3.3V, 50mA, NRND","metaDescription":"Texas Instruments LP2980AIM5-3.3 fixed 3.3V LDO, 50mA output, 0.22V dropout, 63dB PSRR, SOT-23-5.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","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":"Not For New Designs","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)":"3.3V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.3100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3f92094f6ce0d469903428f7d72f839d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LP2980AIM5-3.3/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LP2980AIM5-3.3","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LP2980AIM5-3.3 when reusing this data.
