|---|---|---|---|---|
| FFF Compatibility | Matches the TO-220-3 package of the original LT1584CT with the identical pin-to-pin mapping (1=ADJ, 2=VOUT, 3=VIN).Uses the same standard through-hole TO-220 package profile and mechanical dimensions.Supports a lower maximum output current (5A vs. the original 7A). Can only be used if the system load does not exceed 5A. | Requires a 5-pin TO-220-5 footprint instead of the 3-pin TO-220-3 footprint of the LT1584CT, requiring PCB redesign.Standard TO-220 outline but possesses 5 pins instead of 3.Exceeds the 7A output current capability (provides up to 7.5A) and maintains high efficiency with very low quiescent current. | ||
 AI Summary | LT1584CT by Analog Devices: Linear Voltage Regulator IC 1 Output TO-220-3. | The LM1084IT-ADJ/NOPB is a highly reliable, active 5A adjustable linear regulator that serves as a direct footprint and pinout drop-in replacement for the LT1584CT. It is ideal for designs where the actual load current does not exceed 5A, offering excellent line/load regulation and thermal protection. If the full 7A current capability of the original regulator is required, a board modification to a 5-pin device is necessary.
| The TPS75901KC is a high-performance 7.5A adjustable LDO from Texas Instruments that fully covers the electrical output current requirement of the LT1584CT. While it requires a PCB redesign due to its 5-pin TO-220 package, it offers modern features such as power-good monitoring and shutdown control. This is the recommended choice if the application strictly demands more than 5A of continuous current.

All your BOM, at once
Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.
Hear about problems before they hit production
Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.
Qualified replacements in minutes, not days
Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
Frequently asked questions
Yes. The Analog Devices LT1584CT is marked obsolete, so the manufacturer has discontinued it and any remaining supply is limited to distributor stock. The qualified second sources on this page are active parts you can design in today.
The closest qualified second sources for the Analog Devices LT1584CT are the LM1084IT-ADJ/NOPB (Texas Instruments) and the TPS75901KC (Texas Instruments), out of 3 matched alternatives in total. Each is compared against the original on fit, form and function in the table above.
Not always. The alternatives to the LT1584CT are matched on function but can differ in package, pinout or a key parameter, so review the fit/form/function notes in the table and the datasheet before designing one in.
The LT1584CT (Analog Devices) is a part in the Power Management (PMIC) category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
