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 | FB | input | Feedback input for the adjustable output. Connect the mid-point of an external resistor divider from OUT to GND here to program VOUT from 1.205 V to 8.8 V. Internal reference is 1.2 V (typ); feedback bias current is ~2 nA. |+| 2 | GND | power_in | Device ground return. All voltages are referenced to this pin. |+| 3 | NC | unconnected | No connect. Not connected internally; tie to ground for best thermal performance or leave floating. |+| 4 | IN | power_in | Input supply pin, 2.5 V to 10 V operating range (30 V absolute max on the new chip). Bypass to GND with a 0.1 µF or larger capacitor (0.047 µF or larger for the legacy chip). |+| 5 | OUT | power_out | Regulated output, up to 80 mA. Requires a 1 µF or larger capacitor to GND for stability on the new chip (≥0.47 µF for the legacy chip). Dropout is ~415 mV at 50 mA / ~650 mV at 80 mA. |++## 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.++- `TPS71401DCKT`+- `TPS71401DCKTDCKR`+- `TPS71401DCKTDRVT`+- `TPS71401DCKTDRVR`++## CAD (KiCad official)++- Symbol: `TPS71401DCKT`+- 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/tps714) (None pp, sha256 `3794ea8f66f454a2`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
