Pinout and pin descriptions extracted from the datasheet (via LCSC) by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | VOUT | power_out | Switched output to the load; source of the internal N-channel high-side MOSFET. Voltage tracks VIN minus IOUT*RDS(ON) (typ. 80mΩ). Bypass with an output capacitor to meet USB inrush requirements. |+| 2 | GND | power_in | Device ground reference for internal circuitry and control signals. |+| 3 | ISET | input | Programmable current-limit set pin. Connect a resistor from ISET to GND to set the output current limit (e.g. RISET=10K→~680mA, 6.8K→~1000mA, 3.4K→~2000mA). Present on the adjustable LPW5209AB5F variant. |+| 4 | EN | input | Active-high device enable. VEN(H) ≥ 1.4V turns the switch on; VEN(L) ≤ 0.4V disables it (shutdown current ~0.1µA). Do not float; may be tied to VIN to keep the part permanently enabled. Must not go negative with respect to GND. |+| 5 | VIN | power_in | Input supply pin (2.5V to 6V, abs max 7V) and drain of the internal N-channel MOSFET. Bypass locally with a ceramic input capacitor. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | LOWPOWER |+| Package | SOT-23-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `LPW5209AB5F`+- `LPW5209AB5FLPW5209B5F-21`+- `LPW5209AB5FLPW5209B5F-11`+- `LPW5209AB5FLPW5209B5F-06`++## CAD (KiCad official)++- Symbol: `LPW5209AB5F`+- 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:** [LOWPOWER datasheet](https://datasheet.lcsc.com/datasheet/pdf/dd687ac6877dffc1042938fc7865e51a.pdf) (7 pp, sha256 `def01ef343a1a2c4`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
