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 | VIN | power_in | Supply Voltage Input Pin. Operates from a 4.5V to 40V DC voltage (absolute max 45V). Bypass VIN to GND with a suitably large capacitor to eliminate noise on the input. |+| 2 | OUTPUT | output | Power Switch Output Pin (SW). Output is the internal power transistor switch node that supplies power to the output through the external inductor and Schottky freewheeling diode. Rated for 3A continuous. |+| 3 | GND | power_in | Ground Pin. Care must be taken in layout: this pin should be placed outside of the Schottky diode to output capacitor ground path to prevent switching current spikes from inducing voltage noise into the XL1507. The exposed metal tab is also tied to GND. |+| 4 | FEEDBACK | input | Feedback Pin (FB). Senses the output voltage via an external resistor divider and regulates it. Internal feedback threshold voltage is 1.23V. On the -5.0 fixed version an internal divider (R1=2.5k, R2=7.6k) sets the 5V output. |+| 5 | ON/OFF | input | Enable Pin. Drive ON/OFF pin LOW to turn on the device; drive it HIGH to turn it off. TTL-compatible with hysteresis. Floating defaults low (device ON). Absolute max voltage is VIN. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | XLSEMI XL1507 5 0E1 |+| Package | TO-252-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `XL1507-5.0E15.0E1`++## CAD (KiCad official)++- Symbol: `XL1507-5.0E1`+- Footprint: `Package_TO_SOT_SMD:TO-252-2`+- 3D model: TO-252-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [XLSEMI XL1507 5 0E1 datasheet](docs/xl1507-5-0e1-datasheet.pdf) (12 pp, sha256 `7b23fa3d2ebf161b`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
