It comes in a 6-WSON (2x2 mm) package with an exposed pad for thermal dissipation. The part includes Enable, Power Good, and Soft Start control features, plus protection against over-temperature, reverse polarity, and short circuits. With a quiescent current of 55 µA and a maximum supply current of 600 µA, this LDO is suited for always-on automotive modules — body controllers, sensor interface rails, or CAN transceiver supplies — where standby drain matters. The operating temperature range of -40°C to 125°C (junction) covers under-hood and cabin environments. ## PSRR and dropout — what they mean for the rail PSRR is specified at 80 dB at 100 Hz, rolling to 40 dB at 100 kHz. That 80 dB at line-frequency ripple is what cleans up the output from a switching pre-regulator or alternator noise; the roll-off above audio band means the LDO still provides meaningful rejection into the hundreds of kHz, but a downstream filter cap may be needed if the load is sensitive above 100 kHz. For a 3 V rail feeding an analog sensor or ADC reference, this PSRR profile is the main selection parameter. Maximum dropout voltage is 0.25 V at 500 mA. The 6.5 V maximum input gives margin for automotive load-dump transients if protected externally. ## Lifecycle and sourcing posture The LP5912Q3.0DRVTQ1 is listed as Active on TI's product status. It is ROHS3 compliant. No LTB or NRND notice is in effect.","metaTitle":"LP5912Q3.0DRVTQ1 Automotive LDO, 3V 500mA, AEC-Q100","metaDescription":"TI LP5912Q3.0DRVTQ1 is an AEC-Q100 qualified LDO, fixed 3V output, 500mA, 55µA Iq, 80dB PSRR at 100Hz.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"PSRR":"80dB ~ 40db (100Hz ~ 100kHz)","Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"6-WDFN Exposed Pad","lifecycle_stage":"eol_hot","Control Features":"Enable, Power Good, Soft Start","Current - Output":"500mA","Protection Features":"Over Temperature, Reverse Polarity, Short Circuit","Number of Regulators":"1","Output Configuration":"Positive","Operating Temperature":"-40°C ~ 125°C (TJ)","Voltage - Input (Max)":"6.5V","Voltage Dropout (Max)":"0.25V @ 500mA","Current - Supply (Max)":"600 µA","Supplier Device Package":"6-WSON (2x2)","Current - Quiescent (Iq)":"55 µA","Voltage - Output (Min/Fixed)":"3V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.67","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.67000","currency":"USD"},{"qty":10,"price":"$1.50300","currency":"USD"},{"qty":25,"price":"$1.41760","currency":"USD"},{"qty":100,"price":"$1.20790","currency":"USD"},{"qty":250,"price":"$1.13420","currency":"USD"},{"qty":500,"price":"$0.99242","currency":"USD"},{"qty":1250,"price":"$0.82230","currency":"USD"},{"qty":2500,"price":"$0.80250","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/c86ef80cbf17b07595ec6653fd6f17f7.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is LP5912Q3.0DRVTQ1 AEC-Q100 qualified?","answer":"Yes, this LDO is part of TI's Automotive series and carries AEC-Q100 qualification, making it suitable for automotive-grade BOM lines."},{"question":"What is the PSRR of LP5912Q3.0DRVTQ1?","answer":"PSRR is specified as 80 dB at 100 Hz, decreasing to 40 dB at 100 kHz."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LP5912Q3.0DRVTQ1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LP5912Q3.0DRVTQ1 when reusing this data.
