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 | VIN | power_in | Power input voltage. Recommended operating range 2.5V to 5.5V (absolute max 6.5V). Requires a >=1µF input capacitor placed within 0.5 inch of the pin. |+| 2 | GND | power_in | Device ground return. Return input and output capacitors to a clean analog ground. |+| 3 | EN | input | Chip enable (active high, TTL logic). VIH >= 1.4V enables the regulator; VIL <= 0.4V places the device in shutdown (<0.01µA typical). May be tied to VIN for always-on operation. Absolute max EN voltage is VIN+0.3V. |+| 4 | NC | unconnected | No internal connection. May be left floating. |+| 5 | VOUT | power_out | Regulated 3.3V output (±3% accuracy at 1mA). Delivers up to 300mA with 220mV typical dropout at 300mA. Requires a >=1µF ceramic output capacitor (ESR >25mΩ acceptable) placed within 0.5 inch of the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | LOWPOWER |+| Package | SOT-23-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `LP3992-33B5FB5F`+- `LP3992-33B5FJ5F`+- `LP3992-33B5FB3F`++## CAD (KiCad official)++- Symbol: `LP3992-33B5F`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT-23-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [LOWPOWER datasheet](docs/lp3992-33b5f-datasheet.pdf) (9 pp, sha256 `c4874862660fdd11`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
