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 4.5V to 40V DC. Bypass VIN to GND with a suitably large capacitor (e.g. 470uF/35V) to eliminate input noise. Absolute max -0.3 to 45V. |+| 2 | OUTPUT | output | Power Switch Output Pin (SW). Switch node that connects to the external inductor and catch (Schottky) diode to supply power to the output. Capable of 3A output current. |+| 3 | GND | power_in | Ground Pin. Care must be taken in layout: this pin should be placed outside the Schottky diode to output-capacitor ground path to prevent switching current spikes from inducing voltage noise into XL1507. The metal tab is also connected to GND. |+| 4 | FEEDBACK | input | Feedback Pin (FB). Through an external resistor divider network, senses the output voltage and regulates it. Internal feedback threshold voltage is 1.23V (typ, min 1.193V, max 1.267V). Absolute max -0.3V to VIN. |+| 5 | ON/OFF | input | Enable Pin. Drive ON/OFF pin LOW to turn the device on; drive HIGH to turn it off. Floating defaults to low (device on). TTL compatible with hysteresis. Absolute max -0.3V to VIN. |+| TAB | GND | power_in | Metal Tab electrically connected to GND. Provides thermal dissipation path; solder to a ground copper pour to reduce junction-to-ambient thermal resistance (RJA typ 50 C/W without heatsink). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | XLSEMI |+| Package | TO-252-5 |+| Category | PMIC |+| Pins | 6 |++## Ordering variants++- `XL1507-ADJE1ADJE1`+- `XL1507-ADJE15.0E1`++## CAD (KiCad official)++- Symbol: `XL1507-ADJE1`+- 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 datasheet](docs/xl1507-adje1-datasheet.pdf) (12 pp, sha256 `7b23fa3d2ebf161b`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
