That level of rejection matters when the regulator powers a precision analog front-end — an ADC reference, an op-amp supply, or a VCO bias — where 1 kHz switching ripple from a downstream DC-DC converter would otherwise couple into the signal path. Below 50 mA output, the dropout voltage maxes at 0.22 V, keeping headroom loss tight on a 3.3 V rail. ## Package and temperature grade — the 5-µSMD constraint This is not a hand-solderable part; it requires a solder-paste stencil, a reflow profile matched to the µSMD's thermal mass, and X-ray inspection for voiding and ball wetting. The quiescent current sits at 95 µA, a reasonable figure for always-on or battery-backed rails. The regulator integrates over-current, over-temperature, and short-circuit protection — standard for a modern LDO but worth noting for a design that cannot tolerate a latched fault on a 3.3 V analog rail. An Enable pin allows the rail to be gated by a system supervisor or GPIO, cutting the 95 µA quiescent draw when the load is idle.","metaTitle":"LP2980AITP-3.3/NOPB LDO Regulator, 50 mA, 3.3 V Fixed","metaDescription":"Texas Instruments LP2980AITP-3.3/NOPB LDO, 50 mA fixed 3.3 V output, PSRR 63 dB at 1 kHz, -40°C to 125°C.","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/3f92094f6ce0d469903428f7d72f839d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LP2980AITP-3.3%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for LP2980AITP-3.3/NOPB?","answer":"The evidence does not list an official successor order code from Texas Instruments.
