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 | EN | input | Enable input, active high. Logic high (VIH ≥ 1.0V) turns the regulator on; logic low (VIL ≤ 0.3V) shuts it down. Internal ~3.0MΩ pull-down to GND. EN leakage ±0.1µA at VIN=5.5V. |+| 2 | GND | power_in | Device ground reference. Also serves as the thermal/mechanical tab on the SOT89-5 package. |+| 3 | ADJ/NC | input | On the adjustable variant this is the ADJ feedback input (VREF = 0.8V nominal, IADJ ≤ 0.5µA); a resistor divider from OUT to this pin and GND sets VOUT. On fixed-output variants (including AP7361C-33) this pin is a no-connect internally. |+| 4 | IN | power_in | Regulator input. VIN operating range 2.2V to 6.0V (absolute max 6.5V). Bypass to GND with at least 1µF ceramic capacitor (4.7µF recommended). |+| 5 | OUT | power_out | Regulated output, 3.3V fixed on the -33 variant, up to 1A continuous. Bypass to GND with at least 2.2µF ceramic capacitor (4.7µF recommended); larger COUT improves ac load response. Internal ~100Ω output discharge resistor. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Diodes Incorporated |+| Package | SOT-89-5 |+| Category | PMIC |+| Pins | 5 |++## Ordering variants++- `AP7361C-33Y5-1333Y5-13`++## CAD (KiCad official)++- Symbol: `AP7361C-33Y5-13`+- Footprint: `Package_TO_SOT_SMD:SOT-89-3`+- 3D model: SOT-89-5 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Diodes Incorporated datasheet](https://www.diodes.com/assets/Datasheets/AP7361C-33Y5-13.pdf) (22 pp, sha256 `9b64f49c5975b2ba`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
