A 63 dB PSRR at 1 kHz means this regulator attenuates ripple on the input by roughly 1,400× at that frequency — enough to keep a 100 mVpp input buzz down to ~70 µVpp on the 3.3 V output. The 0.22 V maximum dropout at 50 mA tells you the input must stay above 3.52 V to maintain regulation; below that the output follows the input minus the dropout floor. That Iq is low enough for battery-powered always-on blocks, but not the single-digit-microamp territory of dedicated ultra-low-Iq LDOs. ## Industrial temperature range — not a commercial-grade part Protection features include over-current, over-temperature, and short-circuit — standard for a modern LDO, but the over-temperature shutdown is what keeps the die safe when the µSMD's thermal resistance is pushed in a tight layout. The 5-µSMD package and the NOPB (lead-free) finish are fixed; there is no drop-in replacement from TI's current portfolio with the same footprint and pinout.","metaTitle":"LP2980AIBP-3.3/NOPB LDO Regulator, 3.3V Fixed, 50mA","metaDescription":"Texas Instruments LP2980AIBP-3.3/NOPB is a 50mA LDO with 3.3V fixed output, PSRR 63dB at 1kHz, -40°C to 125°C range.","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":"5-VFBGA","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":"5-µSMD (0.93x1.11)","Current - Quiescent (Iq)":"95 µA","Voltage - Output (Min/Fixed)":"3.3V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/eabcfdbdb17bcf38ee7ef2c6d535c154.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LP2980AIBP-3.3%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"What is the recommended replacement for LP2980AIBP-3.3/NOPB?","answer":"Any replacement must be evaluated for pinout, dropout, PSRR, and package compatibility — the 5-µSMD footprint is unusual and may not have a direct drop-in from current production."},{"question":"What is LP2980AIBP-3.3/NOPB's PSRR at 1 kHz?","answer":"The PSRR is 63 dB at 1 kHz.
