It is built for space-constrained, battery-powered or low-noise analog rails where every millivolt of headroom counts. The part comes in a 4-DSBGA package measuring 1x1 mm, which suits compact wireless modules, portable medical devices, and sensor nodes. Enable control and protection against over-temperature and short circuit are included on-chip. ## Dropout and quiescent current — the battery-design numbers At the full 150 mA load the maximum dropout voltage is 0.2 V. The quiescent current is 80 µA typical, rising to 120 µA maximum under all conditions. ## PSRR across the audio band Power-supply rejection ratio is specified as 55 dB at 1 kHz and 35 dB at 10 kHz. ## Temperature range and package handling The operating temperature range is -40°C to 85°C, which covers industrial and outdoor telecom enclosures. The 4-DSBGA package has no leads; it is a wafer-level chip-scale package with solder bumps on the bottom. Rework requires a hot-air station with a fine nozzle and careful alignment — the 1x1 mm body leaves little room for error. For prototyping, the Cut Tape option lets you order a few pieces without committing to a full reel. ## Lifecycle and sourcing The LP3990TLX-2.5/NOPB carries an Active product status. The ROHS3 compliance mark means it meets the latest EU restriction levels. For BOM planning, this part is a safe choice for new designs — no near-term obsolescence risk.","metaTitle":"LP3990TLX-2.5/NOPB LDO Regulator, 2.5V Fixed Output, 150mA","metaDescription":"TI LP3990TLX-2.5/NOPB LDO: 2.5V fixed output, 150mA, 0.2V dropout at full load, 80µA quiescent current, PSRR 55dB~35dB, -40°C to 85°C, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"PSRR":"55dB ~ 35dB (1kHz ~ 10kHz)","Package":"Tape & Reel (TR); Cut Tape (CT)","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"4-WFBGA, DSBGA","lifecycle_stage":"eol_hot","Control Features":"Enable","Current - Output":"150mA","Protection Features":"Over Temperature, Short Circuit","Number of Regulators":"1","Output Configuration":"Positive","Operating Temperature":"-40°C ~ 85°C","Voltage - Input (Max)":"6V","Voltage Dropout (Max)":"0.2V @ 150mA","Current - Supply (Max)":"120 µA","Supplier Device Package":"4-DSBGA (1x1)","Current - Quiescent (Iq)":"80 µA","Voltage - Output (Min/Fixed)":"2.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.96","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.96000","currency":"USD"},{"qty":10,"price":"$0.84700","currency":"USD"},{"qty":25,"price":"$0.79520","currency":"USD"},{"qty":100,"price":"$0.64900","currency":"USD"},{"qty":250,"price":"$0.60284","currency":"USD"},{"qty":500,"price":"$0.51304","currency":"USD"},{"qty":1000,"price":"$0.41043","currency":"USD"},{"qty":3000,"price":"$0.37195","currency":"USD"},{"qty":6000,"price":"$0.36300","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/343b93ba5a74788be3e584100b5d908a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is LP3990TLX-2.5/NOPB suitable for battery-powered applications?","answer":"Yes.
