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) ceramic capacitor between BST and SW to supply gate-drive voltage to the internal top N-channel MOSFET. Absolute maximum: SW-0.3V to SW+5V. |+| 2 | GND | power_in | Device ground return. Connect to the system ground plane with a low-impedance path; place the input decoupling capacitor close to VIN/GND to minimize loop area. |+| 3 | FB | input | Output feedback pin. FB senses the divided output voltage and is regulated by the internal error amplifier to the 800mV (typ) reference. Connect a resistive divider from Vout to FB to GND to set the output voltage. Absolute maximum: -0.3V to 6V. |+| 4 | EN | input | Enable input. Drive EN high (>1.3V typ) to turn on the regulator; drive low (<0.3V) to shut down. Can be tied to VIN through a resistive divider to implement programmable input UVLO. Absolute maximum: -0.3V to 44V. |+| 5 | VIN | power_in | Input supply pin, 4.7V to 40V. Powers the IC and the internal top power switch. Bypass VIN to GND with a low-ESR ceramic capacitor (typ 4.7uF X5R/X7R) placed close to the pin. |+| 6 | SW | output | Switching node. Internal top and bottom N-channel MOSFETs (RDS(on) ~500m/220m ohm) connect here. Attach the external inductor from SW to the output and the BST capacitor from SW to BST. Absolute maximum: -0.3V to 44V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | JoulWatt Tech |+| Package | SOT-23-6 |+| Category | PMIC |+| Pins | 6 |++## Ordering variants++Same part, different packaging or reel option.++- `JW5026SOTB#PBF`+- `JW5026SOTB#TRPBF`++## CAD (KiCad official)++- Symbol: `JW5026SOTB#TRPBF`+- 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/jw5026sotb-trpbf-datasheet.pdf) (11 pp, sha256 `c75944daefa427c7`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
