Pins 3 and 4 are both IN. |+| 4 | IN | power_in | Input voltage pin; the datasheet's recommended input range is 2.7 V to 10 V, with VIN at least VOUT + VDO or 2.7 V, whichever is greater. Pins 3 and 4 are both IN. |+| 5 | OUT | power_out | Regulated output voltage pin; a capacitor of at least 10 µF with ESR between 60 mΩ and 1.5 Ω is required between OUT and GND. |+| 6 | OUT | power_out | Regulated output voltage pin; a capacitor of at least 10 µF with ESR between 60 mΩ and 1.5 Ω is required between OUT and GND. Pins 5 and 6 are both OUT. |+| 7 | FB/NC | unconnected | Feedback input for the adjustable version only; on the fixed-output TPS76825 it is a no-connect pin. |+| 8 | PG | output | Open-drain power-good output that goes low when the output falls to between 92% and 98% of nominal and requires an external pullup resistor, or can be left floating if unused. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-8 |+| Category | Power Management (PMIC) |+| Pins | 8 |++## CAD (KiCad official)++- Symbol: `TPS76825QD`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)+- 3D model files: `tps76825qd-etched.step` / `tps76825qd-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tps76825qd.step` / `tps76825qd.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/tps768) (31 pp, sha256 `742896d0a1cf7766`, retrieved 2026-10-08, tier: lcsc)+- **Extractor:** parts-factory `2.0.0` / `extract_pins 0.3`, primary `claude-haiku-5-5` (text), consensus `claude-sonnet-5-5` (agreed), guards: pin_guards 0.1: passed.
