|---|---|---|---|---|
| FFF Compatibility | Exact same package (8-VSSOP / MSOP-8) and identical pinout. No land pattern modifications are needed.Identical package shape, dimensions, and mounting style.Exact same electrical parameters and characteristics, featuring RoHS compliance. | Pinout is completely identical (1: OUT, 2: IN, 3: GND, 4: OUT, 5: SET, 6: CC, 7: SHDN, 8: FAULT) in a physically matching 8-pin uMAX (MSOP) package.Standard 8-pin uMAX (MSOP) package is fully interchangeable with the target's 8-VSSOP package.Meets all critical parameters. Dual-Mode operation overrides the 3.3V preset, allowing adjustable operation via external resistors connected to the SET pin. | ||
 AI Summary | LP3982IMM-ADJ by Texas Instruments: Linear Voltage Regulator IC Positive Adjustable 1 Output 300mA 8-VSSOP. | The LP3982IMM-ADJ/NOPB is the direct RoHS-compliant / Pb-free replacement for the obsolete LP3982IMM-ADJ. It is an active part from the same manufacturer, offering the exact same 300mA output current, adjustable voltage range, and electrical characteristics without requiring any design modifications.
| The MAX8860 series is explicitly designed by the manufacturer to be pin, package, and performance compatible with the LP3982. When configured with external feedback resistors on the SET pin (Dual-Mode), it acts as an adjustable LDO operating identically to the original part, with a slightly wider input range up to 6.5V.

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 Texas Instruments LP3982IMM-ADJ 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 Texas Instruments LP3982IMM-ADJ are the LP3982IMM-ADJ/NOPB (Texas Instruments) and the MAX8860EUA33+ (Analog Devices / Maxim Integrated), out of 4 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 LP3982IMM-ADJ 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 LP3982IMM-ADJ (Texas Instruments) is a part in the Power Management (PMIC) category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
