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 | Regulator power input. Operating range 1.2V to 5.5V; absolute max -0.3V to 6.5V referenced to GND. Bypass to GND with 1µF to 10µF ceramic or tantalum capacitor close to the pin. |+| 2 | GND | power_in | Ground reference for the regulator. Common return for VIN bypass, VOUT bypass, and EN logic. |+| 3 | EN | input | Enable input. Logic high (VIH ≥ 2V) turns the regulator on; logic low (VIL ≤ 0.6V) puts the device in shutdown (~10nA typical). EN input current ~10nA at VEN=5V; absolute max -0.3V to 6V. Do not leave floating. |+| 4 | NC | unconnected | No internal connection. Leave floating or tie to GND per layout preference. |+| 5 | VOUT | power_out | Regulated 3.3V output, up to 600mA. ±2% accuracy. Requires 1µF to 10µF ceramic or tantalum output capacitor for stability. Absolute max -0.3V to 6V to GND; -6V to 0.3V referenced to VIN. Internal ~100Ω discharge resistor active when EN=0V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | TECH PUBLIC TPAP2112K 3 3TRG1 |+| Package | SOT-23-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `TPAP2112K-3.3TRG1TRG1`++## CAD (KiCad official)++- Symbol: `TPAP2112K-3.3TRG1`+- 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 TPAP2112K 3 3TRG1 datasheet](docs/tpap2112k-3-3trg1-datasheet.pdf) (9 pp, sha256 `f812f394a492b5c8`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
