Its 63 dB PSRR at 1 kHz means it knocks down switching supply ripple by a factor of roughly 1400, which is the difference between a noisy digital rail and a clean analog supply for an op-amp or ADC reference. ## Dropout and headroom — the real-world margin Maximum dropout is 0.22 V at the full 50 mA load. That means with a 3.3 V output, the input can sag to 3.52 V and the regulator still holds regulation. In a battery-powered design with a 3.7 V Li-ion cell, that buys useful run time before the undervoltage lockout kicks in. Input voltage range extends to 16 V, so the part can also drop from a 5 V or 12 V rail without issue. ## Protection features that matter on a production board Built-in over-current, over-temperature, and short-circuit protection mean the regulator survives a miswired load or a bench fault without latching off or failing short. No last-time-buy notice, no end-of-life clock.","metaTitle":"LP2980AIM5-3.3/NOPB LDO Regulator, 3.3V Fixed, 50mA","metaDescription":"Texas Instruments LP2980AIM5-3.3/NOPB LDO voltage regulator, fixed 3.3V output, 50mA, 63dB PSRR at 1kHz, 95µA Iq, SOT-23-5.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"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":"Active","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":"$0.9800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3f92094f6ce0d469903428f7d72f839d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LP2980AIM5-3.3%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"What is the PSRR of LP2980AIM5-3.3/NOPB?","answer":"PSRR is 63 dB at 1 kHz.
