**Diodes Incorporated** · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-25

AP7366-30W5-7 from Diodes Incorporated, in a SOT-25. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model). Symbol and footprint from KiCad-official CAD; the 3D model is generated from the datasheet's package dimensions.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | IN | power_in | Voltage input pin; bypass to ground through at least 1µF MLCC capacitor, with VIN specified from 2.2V to 6V (absolute maximum 6.5V). |
| 2 | GND | power_in | Ground pin. |
| 3 | EN | input | Enable input, active high: the device is on when EN is logic-high (VIH minimum 1.0V) and off when EN is at logic-low (VIL maximum 0.3V). |
| 4 | NC | unconnected | No connection on the fixed-output SOT25 variant. |
| 5 | OUT | power_out | Voltage output pin for the fixed 3.0V output; bypass to ground through a 1µF MLCC capacitor, with IOUT up to 600mA. |

## CAD (land: KiCad; 3D: generated from the datasheet)

- Symbol: `AP7366-30W5-7`
- Footprint: `Package_TO_SOT_SMD:SOT-23-5`
- 3D model: SOT-25, generated on the KiCad land (body 1.6 x 2.8 mm, terminals on the pads, 1.1 mm tall, datasheet A, nominal). KiCad's stock model for this land is taller than the datasheet allows, so the model is generated from the datasheet drawing; the dimensions come from the datasheet drawing where it was read and are defaults otherwise (see provenance.model_3d_generated), not the manufacturer's CAD (STEP)
- 3D model files: `ap7366-30w5-7-etched.step` / `ap7366-30w5-7-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ap7366-30w5-7.step` / `ap7366-30w5-7.glb` are the bare package body.
