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 | BST | passive | Bootstrap pin for the top switch driver. Connect a 0.1uF (or larger) capacitor between BST and SW to supply gate-drive current to the internal high-side N-channel MOSFET. Absolute maximum voltage is SW-0.3V to SW+5V. |+| 2 | GND | power_in | Device ground. Return path for internal circuitry and the low-side power MOSFET. |+| 3 | FB | input | Output voltage feedback pin. FB is regulated by the internal control loop to 800mV (typ). Connect a resistive divider from Vout to FB to GND to set the output voltage. |+| 4 | EN | input | Enable input. Drive EN high to turn on the regulator; drive low to shut down. Shutdown threshold is 1.3V typical (1.18V min / 1.42V max) with 120mV typical hysteresis. Absolute maximum voltage is -0.3V to 44V. |+| 5 | VIN | power_in | Input supply pin. Accepts 4.7V to 40V. Bypass VIN to GND with a suitably large ceramic capacitor (e.g. 4.7uF) close to the pin to filter input noise. Absolute maximum voltage is -0.3V to 44V. |+| 6 | SW | power_out | Switching node connecting the drain of the internal high-side and low-side MOSFETs. Connect the external inductor of the output LC filter from SW to the load. Absolute maximum voltage is -0.3V (-7V for 5ns) to 44V (45V for 5ns). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | JoulWatt Tech |+| Package | SOT-23-6 |+| Category | PMIC |+| Pins | 6 |++## Ordering variants++- `JW5026SOTB#TRPBF`++## CAD (KiCad official)++- Symbol: `JW5026`+- Footprint: `Package_TO_SOT_SMD:SOT-23-6`+- 3D model: SOT-23-6 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [JoulWatt Tech datasheet](docs/jw5026-datasheet.pdf) (12 pp, sha256 `31a1b41d6483c408`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
