Operating temperature spans -40°C to 125°C, qualifying it for industrial enclosures, outdoor telecom cabinets, and under-hood automotive modules that see underhood ambient peaks. ## Protection set and control interface Built-in over-current, over-temperature, and reverse-polarity protection reduce the need for external clamp diodes or foldback circuits. The Enable and Power Good pins allow sequencing against an FPGA or MCU power-up sequence — Power Good asserts when the output is within regulation, so the load can be released from reset cleanly. Quiescent current runs 3.5 mA typical, supply current maxes at 60 mA. Not a micropower LDO, but the 3 A capability and protection set suit it for point-of-load regulation where the load current dominates the power budget anyway. ## Lifecycle and sourcing posture The LT3033EUDC#TRPBF carries an Active product status with ROHS3 compliance. No end-of-life notice or last-time-buy schedule is in effect, so it remains qualified for new designs and production ramps without a looming LTB window.","metaTitle":"LT3033EUDC#TRPBF LDO Regulator, 3A Adjustable, 0.24V Dropout","metaDescription":"LT3033EUDC#TRPBF from Analog Devices: 3A positive adjustable LDO, 0.2V to 9.7V output, 0.24V max dropout at 3A, PSRR 60dB~52dB (120Hz~1MHz), 20-QFN 3x4, -40°C","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"PSRR":"60dB ~ 52dB (120Hz ~ 1MHz)","Package":"Tape & Reel (TR); Cut Tape (CT)","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"20-WFQFN Exposed Pad","lifecycle_stage":"eol_hot","Control Features":"Enable, Power Good","Current - Output":"3A","Protection Features":"Over Current, Over Temperature, Reverse Polarity","Number of Regulators":"1","Output Configuration":"Positive","Operating Temperature":"-40°C ~ 125°C","Voltage - Input (Max)":"10V","Voltage Dropout (Max)":"0.24V @ 3A","Current - Supply (Max)":"60 mA","Voltage - Output (Max)":"9.7V","Supplier Device Package":"20-QFN (3x4)","Current - Quiescent (Iq)":"3.5 mA","Voltage - Output (Min/Fixed)":"0.2V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.08","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$9.08000","currency":"USD"},{"qty":10,"price":"$8.20400","currency":"USD"},{"qty":25,"price":"$7.82280","currency":"USD"},{"qty":100,"price":"$6.79250","currency":"USD"},{"qty":250,"price":"$6.48720","currency":"USD"},{"qty":500,"price":"$5.91480","currency":"USD"},{"qty":1000,"price":"$5.40000","currency":"USD"},{"qty":2500,"price":"$5.40000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/40a3ddeea26e18dd5ab0dc48b81ae7a2.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy LT3033EUDC#TRPBF and get current pricing?","answer":"Submit an RFQ to receive a firm price and availability commitment — no stock or lead-time number is published here, but the quote confirms both before any order is placed."},{"question":"Does LT3033EUDC have reverse polarity protection?","answer":"Yes, reverse polarity protection is included in the protection feature set, along with over-current and over-temperature shutdown."},{"question":"How does LT3033EUDC compare to the LT3042IMSE#TRPBF?","answer":"The LT3042 is a 200 mA LDO with higher PSRR (117 dB at 120 Hz) and a 20 V input maximum, but it delivers only 200 mA.
