AP7361C-33Y5-13 from Diodes Incorporated, in a SOT-89-5. 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. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 582 faces against 26 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
