Its PSRR is 117 dB at 120 Hz rolling off to 53 dB at 10 MHz. Maximum dropout at full load is 0.45 V. Output is adjustable from 0 V to 15 V via external resistors. ## Rated for the harsh edge The junction temperature range is -55°C to 125°C. The 10-DFN (3x3 mm) exposed-pad package pulls heat into the PCB copper. Protection features include over-current, over-temperature, reverse polarity, and under-voltage lockout. ## Sourcing and lifecycle The LT3045MPDD#PBF is listed as Active with ROHS3 compliance. For dual-sourcing consideration, the LT3045EMSE#PBF is a close functional sibling in an MSOP-12 package with a -40°C to 125°C temperature range — same PSRR, same output current, but a different footprint and a slightly narrower temperature grade.","metaTitle":"LT3045MPDD#PBF LDO Regulator, 500 mA, 117 dB PSRR","metaDescription":"Analog Devices LT3045MPDD#PBF positive adjustable LDO, 500 mA output, 117 dB PSRR at 120 Hz, 0.45 V dropout, -55 to 125°C, 10-DFN.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"PSRR":"117dB ~ 53dB (120Hz ~ 10MHz)","Package":"Tube","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"10-WFDFN Exposed Pad","lifecycle_stage":"eol_hot","Control Features":"Enable, Power Good","Current - Output":"500mA","Protection Features":"Over Current, Over Temperature, Reverse Polarity, Under Voltage Lockout (UVLO)","Number of Regulators":"1","Output Configuration":"Positive","Operating Temperature":"-55°C ~ 125°C (TJ)","Voltage - Input (Max)":"20V","Voltage Dropout (Max)":"0.45V @ 500mA","Current - Supply (Max)":"25 mA","Voltage - Output (Max)":"15V","Supplier Device Package":"10-DFN (3x3)","Voltage - Output (Min/Fixed)":"0V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$19.81","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$19.81000","currency":"USD"},{"qty":10,"price":"$18.20800","currency":"USD"},{"qty":25,"price":"$17.45280","currency":"USD"},{"qty":100,"price":"$15.37740","currency":"USD"},{"qty":250,"price":"$14.62272","currency":"USD"},{"qty":500,"price":"$13.67930","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/47d3f87b5195c2d384a5b3397f89bcb4.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is LT3045MPDD#PBF RoHS compliant?","answer":"Yes, it is ROHS3 compliant."},{"question":"What is the equivalent or replacement for LT3045MPDD#PBF?","answer":"The LT3045EMSE#PBF is a close functional equivalent with the same 500 mA output and PSRR, but in an MSOP-12 package and rated -40°C to 125°C.
