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 | Unregulated input supply voltage. Operating range up to 18V (absolute max 18V). Bypass to GND with a 1µF ceramic capacitor close to the pin. |+| 2 | GND | power_in | Device ground reference. Connect to the system ground plane. |+| 3 | CE | input | Chip Enable (active-high). VCEH ≥ 1.3V enables the regulator; VCEL ≤ 0.7V disables it and puts the device into low-power shutdown. When CE=0 an internal ~500Ω auto-discharge resistor pulls VOUT to ground. |+| 4 | NC | unconnected | No internal connection. Leave floating or tie to GND. |+| 5 | VOUT | power_out | Regulated 5.0V output (typ, 4.9V min / 5.1V max at IOUT=30mA). Supports up to 300mA continuous with foldback short-circuit protection (ISHORT≈40mA, ILIMIT≈500mA). Requires a 1µF ceramic output capacitor for stability. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | TECH PUBLIC |+| Package | SOT-23-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `TP181C50S5-A`+- `TP181C50S5-AD6`+- `TP181C50S5-AT3`+- `TP181C50S5-AS3L`++## CAD (KiCad official)++- Symbol: `TP181C50S5-A`+- 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:** [TECH PUBLIC datasheet](docs/tp181c50s5-a-datasheet.pdf) (7 pp, sha256 `48f531e81160802a`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
