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 | Operating voltage input. Accepts supply up to 40 V (absolute max VCC = +45 V). Bypass to GND with an input capacitor close to the pin. |+| 2 | Output | output | Switching output from the internal 3 A NPN switch. Connect to the external inductor / catch diode node of the buck power stage. Saturation voltage typically 1.3 V at IOUT = 3 A. |+| 3 | Gnd | power_in | Device ground. The metal tab of the TO263-5L package is internally tied to Gnd and should be soldered to a ground copper pour for thermal dissipation (θJA ≈ 37 °C/W for TO263-5). |+| 4 | FB | input | Output voltage feedback control input. Internal reference VFB = 1.23 V; for the adjustable version set VOUT = VFB × (1 + R1/R2) with R2 = 1 k-3 k. Feedback bias current typically 40 nA (max 100 nA over temperature). |+| 5 | SD | input | ON/OFF shutdown logic input. VIL ≤ 0.6 V keeps the regulator ON; VIH ≥ 2.0 V forces the regulator OFF (standby). Absolute max input range −0.3 V to +40 V. Can be paired with an external RC (e.g. 0.1 µF + 10 k) for a delay-start. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Diodes Incorporated |+| Package | TO-263-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `AP1501-K5G-13`+- `AP1501-K5G-1350K5G-13`+- `AP1501-K5G-1312K5G-13`+- `AP1501-K5G-1333K5G-13`+- `AP1501-K5G-13T5G`+- `AP1501-K5G-13T5RG`++## CAD (KiCad official)++- Symbol: `AP1501-K5G-13`+- Footprint: `Package_TO_SOT_SMD:TO-263-5_TabPin6`+- 3D model: TO-263-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Diodes Incorporated datasheet](https://www.diodes.com/assets/Datasheets/AP1501-K5G-13.pdf) (13 pp, sha256 `bafb5b2d2810633a`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
