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 | OUT | power_out | Regulator output, 1.8V fixed. Bypass to ground with at least 2.2µF ceramic capacitor; a larger capacitor improves AC load response. Delivers up to 1A output current with 1.5A typical current limit and fold-back short-circuit protection (~400mA into hard short). |+| 2 | EN | input | Enable input, active high. VIL ≤ 0.3V (off), VIH ≥ 1.0V up to VIN (on). Internal ~3.0MΩ pull-down keeps the regulator off when the pin floats; input leakage ±0.1µA typ at VIN=5.5V. |+| 3 | NC | unconnected | No internal connection. Leave floating or tie to ground; not required for operation. |+| 4 | GND | power_in | Device ground return. Connect to the system ground plane; on SO-8EP the exposed thermal pad should also be tied to this net to meet the 100°C/W θJA rating. |+| 5 | NC | unconnected | No internal connection. Leave floating or tie to ground; not required for operation. |+| 6 | NC | unconnected | No internal connection. Leave floating or tie to ground; not required for operation. |+| 7 | NC | unconnected | No internal connection. Leave floating or tie to ground; not required for operation. |+| 8 | IN | power_in | Regulator input supply, 2.2V-6.0V (6.5V absolute max). Bypass to ground with at least 1µF ceramic capacitor close to the pin; 4.7µF recommended for the typical application circuit. |+| 9 | EP | passive | Exposed thermal pad on the underside of the SO-8EP package. Solder to a copper ground pour with thermal vias to achieve the 100°C/W θJA rating; electrically tie to GND. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Diodes Incorporated |+| Package | SOIC-8-EP |+| Category | PMIC |+| Pins | 9 |++## Ordering variants++- `AP7361C-18SP-13`+- `AP7361C-18SP-13SPR`+- `AP7361C-18SP-13FGE`+- `AP7361C-18SP-13Y5`+- `AP7361C-18SP-13D`+- `AP7361C-18SP-13DR`+- `AP7361C-18SP-13E`+- `AP7361C-18SP-13ER`++## CAD (KiCad official)++- Symbol: `AP7361C-18SP-13`+- Footprint: `Package_SO:SOIC-8-1EP_3.9x4.9mm_P1.27mm_EP2.29x3mm`+- 3D model: SOIC-8-EP (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Diodes Incorporated datasheet](https://www.diodes.com/assets/Datasheets/AP7361C-18SP-13.pdf) (None pp, sha256 `9b64f49c5975b2ba`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
