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. Tie through a source resistor RS to VS so that shunt current stays between 60µA (IRMIN) and 15mA; the pin regulates to VR = 5.000V (±0.5% initial for the C grade) with respect to pin 2. Absolute-maximum reverse current is 20mA; forward current (pin 2 to pin 1) is limited to 10mA. |+| 2 | - | passive | Negative (anode) terminal of the shunt reference; the low-side return for the 5.000V reverse-breakdown voltage. Typically connected to the circuit ground/common reference node. |+| 3 | N.C. | unconnected | No internal connection. Leave floating or tie to pin 2 (the '-' terminal); do not connect to any other net. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Analog Devices Inc Maxim Integrated |+| Package | SOT-23-3 |+| Category | Power Management (PMIC) |+| Pins | 3 |++## Ordering variants++Same part, different packaging or reel option.++- `LM4040CIM3-5.0+T`+- `LM4040CIM3-5.0+TCEM3-5.0+T`+- `LM4040CIM3-5.0+TCEM3-5.0/V+T`+- `LM4040CIM3-5.0+TCIX3-5.0+T`+- `LM4040CIM3-5.0+TCEX3-5.0+T`++## CAD (KiCad official)++- Symbol: `LM4040CIM3-5.0+T`+- Footprint: `Package_TO_SOT_SMD:SOT-23-3`+- 3D model: SOT-23-3 (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/8589038191001550848) (None pp, sha256 `cb26444d98d751a0`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
