Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | + | passive | Positive (cathode) terminal of the shunt reference. Connect through a source resistor RS to the supply; the device regulates VR = 2.500V across pins 1 (+) and 2 (-). Reverse current must be kept between IRMIN (~65µA typ, 70µA max for D-grade) and 15mA for regulation, and must never exceed 20mA absolute maximum. |+| 2 | - | passive | Negative (anode) terminal of the shunt reference. Typically tied to circuit ground; forward current from anode to cathode must not exceed 10mA absolute maximum. |+| 3 | N.C. | unconnected | No internal connection. Must be left unconnected or tied to pin 2 (negative terminal); do not connect to any other node. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Analog Devices Inc Maxim Integrated |+| Package | SOT-23 |+| Category | Power Management (PMIC) |+| Pins | 3 |++## Ordering variants++Same part, different packaging or reel option.++- `LM4040DIM3-2.5+T`+- `LM4040DIM3-2.5+TDEM3-2.5+T`+- `LM4040DIM3-2.5+TAIM3-2.5+T`+- `LM4040DIM3-2.5+TBIM3-2.5+T`+- `LM4040DIM3-2.5+TCIM3-2.5+T`+- `LM4040DIM3-2.5+TAEM3-2.5+T`+- `LM4040DIM3-2.5+TBEM3-2.5+T`+- `LM4040DIM3-2.5+TCEM3-2.5+T`+- `LM4040DIM3-2.5+TBIM3-2.5/V+T`+- `LM4040DIM3-2.5+TCEM3-2.5/V+T`+- `LM4040DIM3-2.5+TDIX3-2.5+T`+- `LM4040DIM3-2.5+TAIX3-2.5+T`+- `LM4040DIM3-2.5+TBIX3-2.5+T`+- `LM4040DIM3-2.5+TCIX3-2.5+T`+- `LM4040DIM3-2.5+TAEX3-2.5+T`+- `LM4040DIM3-2.5+TBEX3-2.5+T`+- `LM4040DIM3-2.5+TCEX3-2.5+T`+- `LM4040DIM3-2.5+TDEX3-2.5+T`++## CAD (KiCad official)++- Symbol: `LM4040DIM3-2.5+T`+- Footprint: `Package_TO_SOT_SMD:SOT-23`+- 3D model: SOT-23 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Analog Devices Inc Maxim Integrated datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8589924608654159872) (None pp, sha256 `cb26444d98d751a0`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
