Diodes Incorporated · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-25
AP7331-WG-7 from Diodes Incorporated, in a SOT-25. 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 | IN | power_in | Voltage input pin. Operating range 2V to 6V (abs max 7V). Bypass to GND with at least a 1uF capacitor close to the pin. |
| 2 | GND | power_in | Ground return for the regulator. |
| 3 | EN | input | Enable input, active high. Device turns on when EN is at logic high (VIH >= 1.4V); shutdown when low (VIL <= 0.4V). Abs max VIN + 0.3V. EN input current +/- 1uA max. |
| 4 | NC | unconnected | No connection. Leave floating or tie to a static net. |
| 5 | OUT | power_out | Regulated voltage output pin, up to 300mA. Bypass to GND with a 1uF ceramic capacitor (low ESR) for stability. |
