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 | GND | power_in | Ground reference terminal. Common return for the regulator's internal voltage reference, error amplifier, and pass FET. |+| 2 | VOUT | power_out | Regulated output terminal. Delivers fixed 3.3V (typ) at up to 200mA for the TP121C33; requires a 1µF-10µF ceramic output capacitor to GND. Absolute range: GND-0.3V to VIN+0.3V. |+| 3 | VIN | power_in | Unregulated supply input. Absolute maximum 7.0V; must exceed VOUT by the dropout voltage (typ 70mV @ 30mA, 240mV @ 100mA for the 3.3V option). Bypass with 1µF-10µF ceramic to GND. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | TECH PUBLIC |+| Package | SOT-23-3L |+| Category | PMIC |+| Pins | 3 |++## Ordering variants++- `TP121C33S3L`+- `TP121C33S3LT3`++## CAD (KiCad official)++- Symbol: `TP121C33S3L`+- Footprint: `Package_TO_SOT_SMD:SOT-23-3`+- 3D model: SOT-23-3L (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [TECH PUBLIC datasheet](docs/tp121c33s3l-datasheet.pdf) (10 pp, sha256 `ef7573dc12a5e429`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
