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 | GND | power_in | Ground pin. Layout-sensitive: should be placed outside of the Schottky-diode-to-output-capacitor ground path to prevent switching current spikes from inducing voltage noise into the device. |+| 2 | FB | input | Feedback pin. Senses the output voltage through an external resistor divider and regulates it against the internal 1.25V reference. Output voltage set by VOUT = 1.25 * (1 + R2/R1). |+| 3 | SW | power_out | Power switch output pin. Switch node connected to the drain of the internal power PMOS; supplies the switching waveform to the external inductor and freewheeling Schottky diode. Absolute max -0.3V to VIN. The TO263-5L metal tab is also electrically SW. |+| 4 | VC | passive | Internal voltage regulator bypass capacitor pin. Connect a 1 uF (105) ceramic capacitor from VC to VIN to bypass the internal regulator. |+| 5 | VIN | power_in | Supply voltage input pin. Operates from 8V to 36V DC (absolute max 40V). Bypass VIN to GND with a suitably large capacitor (e.g. 220 uF/50V) to eliminate input noise. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | XLSEMI |+| Package | TO-263-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `XL4015E1E1`++## CAD (KiCad official)++- Symbol: `XL4015E1`+- Footprint: `Package_TO_SOT_SMD:TO-263-2`+- 3D model: TO-263-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [XLSEMI datasheet](docs/xl4015e1-datasheet.pdf) (10 pp, sha256 `3c15d21803d94767`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
