An enable pin provides external on/off control for sequencing multiple rails. Maximum dropout voltage is 0.22 V at 50 mA load. For a 5 V output, the input must stay above 5.22 V worst-case to maintain regulation. That 0.22 V floor is typical for a 50 mA LDO of this era — newer parts like the LP5907 achieve lower dropout at higher currents, but the LP2980's 16 V input maximum gives it headroom for unregulated supplies that sag under load. PSRR is 63 dB at 1 kHz, which attenuates a 1 Vpp ripple on the input to about 0.7 mVpp on the output at that frequency. At higher switching frequencies (100 kHz to 1 MHz) the rejection rolls off — if your design uses a switching regulator upstream and needs clean 5 V for an ADC or analog front-end, budget a post-filter or consider a newer LDO with higher bandwidth PSRR. That Iq is acceptable for always-on rails in battery-backed equipment but not competitive with modern ultra-low-Iq LDOs that draw under 10 µA. For a 50 mA load, the efficiency floor is about 98% at dropout — the quiescent loss dominates at light loads. New designs should not target this part; existing BOM lines must be sourced through independent distribution or surplus channels. Date-code spread and packaging condition (sealed reels vs cut tape) vary by lot and are verified per order. ## SOT-23-5 footprint and layout notes The LP2980IM5X-5.0 is supplied in a SOT-23-5 package (also designated SC-74A, SOT-753). The 5-pin footprint is standard for this package family — 0.95 mm pitch, 2.9 mm body length. The output capacitor should be a 1 µF to 10 µF ceramic placed within 5 mm of the output pin for stability. This part is surface-mount only.","metaTitle":"LP2980IM5X-5.0 LDO Regulator, 5V Fixed, 50mA, SOT-23-5","metaDescription":"Texas Instruments LP2980IM5X-5.0 fixed 5V LDO, 50mA output, 0.22V dropout max, 63dB PSRR at 1kHz, -40°C to 125°C, 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); 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)":"5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3f92094f6ce0d469903428f7d72f839d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LP2980IM5X-5.0/alternatives.json"},"ai":{"faq":[{"question":"What is the equivalent for LP2980IM5X-5.0?","answer":"No official pin-compatible drop-in replacement is listed by Texas Instruments. For new designs, consider the LP5907 series (e.g., LP5907UVX-3.3/NOPB) for a 250 mA LDO with better PSRR (90 dB to 60 dB from 100 Hz to 100 kHz) but lower 5.5 V input maximum — note the output voltage and package differ. For a same-voltage 5 V fixed replacement, evaluate the TPS7A02 family or the LMS1587 series, but verify pinout and enable logic as they are not guaranteed drop-in matches."},{"question":"Can I use LP2980IM5-5.0 instead of LP2980IM5X-5.0?","answer":"The LP2980IM5-5.0 is the same base device in a different tape-and-reel packaging suffix. Electrically they are identical — same 5 V fixed output, 50 mA rating, dropout, and temperature range. The 'X' suffix indicates a specific reel quantity or packaging option; functionally they interchange, but verify the reel quantity matches your assembly needs."},{"question":"What is LP2980IM5X-5.0's listed PSRR?","answer":"The LP2980IM5X-5.0 specifies 63 dB PSRR at 1 kHz. This is a moderate ripple-rejection figure — adequate for 50/60 Hz hum and low-frequency switching noise, but it rolls off above 10 kHz. For higher-frequency rejection, the LP5907 family offers 90 dB at 100 Hz tapering to 60 dB at 100 kHz."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LP2980IM5X-5.0","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LP2980IM5X-5.0 when reusing this data.
