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 | CATHODE | passive | Cathode (K) terminal of the shunt voltage reference. Sinks the regulated cathode current (IZ) - recommended operating range 60μA to 15mA - while maintaining VZ = 4.096V above the anode. Absolute maximum continuous cathode current is -10mA to +20mA. |+| 2 | ANODE | passive | Anode (A) terminal of the shunt voltage reference; the low-side / ground return of the two-terminal reference. VZ (4.096V) is developed between CATHODE and ANODE. |+| 3 | NC | unconnected | No internal connection. A parasitic Schottky diode exists between pin 2 (Anode) and pin 3, so pin 3 MUST be left floating or tied to pin 2 (Anode). In applications with high EMI or significant high-frequency switching noise, TI recommends tying this pin to Anode. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOT-23-3 |+| Category | Power Management (PMIC) |+| Pins | 3 |++## Ordering variants++Same part, different packaging or reel option.++- `TL4050B41QDBZRIDBZR`+- `TL4050B41QDBZRIDBZT`+- `TL4050B41QDBZR`+- `TL4050B41QDBZT`+- `TL4050B41QDBZRIDCKR`+- `TL4050B41QDBZRIDCKT`+- `TL4050B41QDBZRQDCKR`+- `TL4050B41QDBZRQDCKT`++## CAD (KiCad official)++- Symbol: `TL4050B41QDBZR`+- 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:** [Texas Instruments datasheet](https://www.ti.com/cn/lit/gpn/tl4050a) (None pp, sha256 `d043c5224a893bec`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
