Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | IN | power_in | Input pin. For best transient response and to minimize input impedance, use the recommended value or larger ceramic capacitor from IN to ground; see the Recommended Operating Conditions table. Place the input capacitor as close to the input of the device as possible. |+| 2 | GND | power_in | Ground pin. This pin must be connected to ground on the board. |+| 3 | EN | input | Enable pin. Driving this pin to logic high enables the device; driving this pin to logic low disables the device. Do not float this pin. If not used, connect EN to IN. |+| 4 | NC | unconnected | No connect pin. This pin is not internally connected. Connect to ground for best thermal performance or leave floating. |+| 5 | OUT | power_out | A 0.47-µF or greater effective capacitance is required from OUT to ground for stability. For best transient response, use a 1-µF or larger ceramic capacitor from OUT to ground. Place the output capacitor as close to output of the device as possible. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOT-23-5 |+| Category | Power Management (PMIC) |+| Pins | 5 |++## CAD (KiCad official)++- Symbol: `TPS78412QDBVRQ1`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT-23-5 (KiCad packages3D, STEP)+- 3D model files: `tps78412qdbvrq1-etched.step` / `tps78412qdbvrq1-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tps78412qdbvrq1.step` / `tps78412qdbvrq1.glb` are the bare package body.++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/cn/lit/gpn/tps784-q1) (56 pp, sha256 `0c6f0cf1abccc5c1`, retrieved 2026-10-05, tier: lcsc)+- **Datasheet language:** Chinese.
