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 | OUT | power_out | Switched power output from the internal 90 mΩ high-side N-channel MOSFET. Delivers up to 500 mA continuous when enabled; current-limited during overcurrent/short-circuit events. Bypass with output capacitor near load. |+| 2 | GND | power_in | Device ground reference. |+| 3 | FAULT | output | Open-drain, active-low fault indicator. Asserts low during overcurrent, thermal shutdown, or reverse-voltage conditions after the fault-blanking interval. Requires an external pull-up resistor to the logic supply. |+| 4 | EN | input | Enable input for the power switch. Active high on STMPS2151 (CMOS/TTL compatible); drive high to turn the output MOSFET on, drive low to disable and enter low-current standby (≤12 µA). |+| 5 | IN | power_in | 2.7 V to 5.5 V supply input to the high-side MOSFET drain and internal control circuitry. Bypass with a ceramic capacitor close to the pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | STMicroelectronics |+| Package | SOT-23-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `STMPS2151STRSTR`+- `STMPS2151STRMTR`+- `STMPS2151STRTTR`++## CAD (KiCad official)++- Symbol: `STMPS2151STR`+- 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:** [STMicroelectronics datasheet](https://www.st.com/resource/en/datasheet/stmps2151str.pdf) (37 pp, sha256 `700138497f100d55`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
