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 | VDD | power_in | Power supply input. Operating range 1.5 V to 5.5 V; absolute max 6 V. Also serves as the switch input (VIN) feeding the P-channel MOSFET to OUT. |+| 2 | GND | power_in | Device ground reference for control logic and output discharge return. |+| 3 | EN | input | Enable input, active high. VIH ≥ 1.2 V, VIL ≤ 0.4 V (VIN = 1.5-5.5 V). Absolute max 6 V. Internal ~10 MΩ pull-down to GND holds the switch off when floating; EN low activates the ~85Ω quick output discharge. |+| 4 | NC | unconnected | No connect. Internally not connected; leave floating or tie to GND/VDD per board convenience. |+| 5 | OUT | power_out | Switched output voltage pin. Delivers up to 2 A continuous with typical RON of 32 mΩ at VIN = 5.5 V. Discharged through ~85Ω to GND when EN is low. Reverse current blocking engages when VOUT exceeds VIN by ~25 mV. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | TECH PUBLIC |+| Package | SOT-23-5 |+| Category | Power Management (PMIC) |+| Pins | 5 |++## Ordering variants++Same part, different packaging or reel option.++- `TPMAX40203AUK+T`++## CAD (KiCad official)++- Symbol: `TPMAX40203AUK+T`+- 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/tpmax40203auk-t-datasheet.pdf) (6 pp, sha256 `3420b88b31fec35e`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
