# AP7343DQ-18W5-7

**Diodes Incorporated** · Linear Voltage Regulators (LDO) · SOT-25

AP7343DQ-18W5-7 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, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VIN | power_in | Power input pin, with a recommended operating input range of 1.7V to 5.25V and an absolute maximum of 6.0V. |
| 2 | GND | power_in | Ground reference pin; a minimum 0.47μF ceramic input capacitor is recommended between VIN and GND. |
| 3 | EN | input | Enable pin must be driven high or low and must not float; high (VEN of 1.3V to 5.25V) enables the regulator and low (up to 0.5V) puts it into shutdown. |
| 4 | NC | unconnected | Not connected internally; recommended to connect to GND to maximize PCB copper for thermal dissipation. |
| 5 | VOUT | power_out | Regulated output pin; this AP7343DQ-18 variant has a fixed 1.8V output with guaranteed output current of 300mA. |

## Materials and finish

As the datasheet states them (page.json `metadata.appearance`; the 3D model's colours follow it).

| Part | Material | Colour / plating | Datasheet says | Page |
|---|---|---|---|---|
| contacts | copper |  | capacitor is recommended between VIN and GND pins to decouple input power supply glitch. This input capacitor must be located as close as possible to the device to ensure input stability and reduce no | 11 |

## CAD (KiCad official)

- Symbol: `AP7343DQ-18W5-7`
- Footprint: `Package_TO_SOT_SMD:SOT-23-5`
- 3D model: SOT-25 (KiCad packages3D, STEP)
- 3D model files: `ap7343dq-18w5-7-etched.step` / `ap7343dq-18w5-7-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ap7343dq-18w5-7.step` / `ap7343dq-18w5-7.glb` are the bare package body.
