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 | NC | unconnected | No internal connection. Leave floating or tie to any convenient net. |+| 2 | A | passive | Anode (正极) of the shunt reference. Normally connected to ground (system return); forms the low side of the internal 1.225 V bandgap shunt element. |+| 3 | K | passive | Cathode (负极) of the shunt reference. Sinks the shunt current supplied through an external series resistor from Vsupply; the regulated output voltage (1.24 V to 10 V, set by the FB divider) appears here relative to the anode. IR range 60 µA to 12 mA. |+| 4 | NC | unconnected | No internal connection. Leave floating or tie to any convenient net. |+| 5 | FB | input | Feedback input for the adjustable reference. An external resistor divider from cathode (K) to anode (A), with its tap connected to FB, programs the cathode-anode voltage to VR = 1.240 V × (1 + R1/R2). High-impedance node - keep divider currents ≫ FB input bias current (~100 nA typ) for best accuracy. HBM ESD rating on FB is 1 kV (vs 2 kV on other pins). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SC-70-5 |+| Category | Power Management (PMIC) |+| Pins | 5 |++## Ordering variants++Same part, different packaging or reel option.++- `LM4041DIM7X-ADJ`+- `LM4041DIM7X-ADJDIM3X`+- `LM4041DIM7X-ADJDIM3`+- `LM4041DIM7X-ADJDIZ`++## CAD (KiCad official)++- Symbol: `LM4041DIM7X-ADJ`+- Footprint: `Package_TO_SOT_SMD:SOT-353_SC-70-5`+- 3D model: SC-70-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/cn/lit/gpn/lm4041-n) (None pp, sha256 `cd8ea9cf52a32021`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
