It generates a regulated negative rail from -1.22 V down to -20 V, making it a fit for generating the negative supply in bipolar op-amp circuits, ADC/DAC reference buffers, or VEE bias in industrial sensor front-ends. The 8-DFN (3x3 mm) exposed-pad package sinks heat into the PCB plane, and the enable pin lets the system sequencer pull the rail down to zero when the load is idle. ## Protection set for industrial and automotive bias rails Over-current, over-temperature, and reverse polarity protection are all built in. Reverse polarity protection is useful when the negative input rail comes from a DC-DC converter. ## Sourcing and lifecycle The LT1964EDD#TRPBF carries an Active lifecycle status and is ROHS3 compliant. It is a current-production part from Analog Devices, available through independent distribution. For a BOM line that needs a negative adjustable LDO at 200 mA, this part is qualified for new designs and carries no last-time-buy risk. The -40°C to 125°C temperature grade qualifies it for industrial and automotive under-hood environments.","metaTitle":"LT1964EDD#TRPBF Negative LDO Regulator, 200mA","metaDescription":"ADI LT1964EDD#TRPBF negative adjustable LDO, 200mA output, 54dB PSRR at 120Hz, -40°C to 125°C, 8-DFN package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"PSRR":"54dB (120Hz)","Package":"Tape & Reel (TR); Cut Tape (CT)","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"8-WFDFN Exposed Pad","lifecycle_stage":"eol_hot","Control Features":"Enable","Current - Output":"200mA","Protection Features":"Over Current, Over Temperature, Reverse Polarity","Number of Regulators":"1","Output Configuration":"Negative","Operating Temperature":"-40°C ~ 125°C","Voltage - Input (Max)":"-20V","Voltage Dropout (Max)":"0.49V @ 200mA","Voltage - Output (Max)":"-20V","Supplier Device Package":"8-DFN (3x3)","Voltage - Output (Min/Fixed)":"-1.22V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.2","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$5.20000","currency":"USD"},{"qty":10,"price":"$4.66700","currency":"USD"},{"qty":25,"price":"$4.41240","currency":"USD"},{"qty":100,"price":"$3.82400","currency":"USD"},{"qty":250,"price":"$3.62784","currency":"USD"},{"qty":500,"price":"$3.25526","currency":"USD"},{"qty":1000,"price":"$2.77500","currency":"USD"},{"qty":2500,"price":"$2.77500","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/1964fb.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the protection features of LT1964EDD#TRPBF?","answer":"Over-current, over-temperature, and reverse polarity protection are all integrated. The reverse polarity protection is particularly valuable when the negative input rail is sourced from a DC-DC converter that may see transient reversal during power sequencing."},{"question":"Can LT1964EDD#TRPBF be used as a positive regulator?","answer":"No — this part is configured for negative output only. It regulates a negative input voltage down to a more negative (or less negative) adjustable output. For a positive adjustable LDO at similar current, look at the LT1761 series."},{"question":"What is the closest functional second-source for LT1964EDD#TRPBF?","answer":"There is no direct pin-compatible second-source from another manufacturer. Within the Analog Devices family, the LT3015IDD#TRPBF is the same negative adjustable topology and same 8-DFN footprint, but it is rated for 1.5 A — a different current tier. The LT1761IS5-SD#TRMPBF is a positive regulator, not a functional substitute for a negative rail design."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/LT1964EDDTRPBF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/LT1964EDDTRPBF when reusing this data.
