Diodes Incorporated · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-25
AP7366EA-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 | IN | power_in | Voltage input pin, recommended operating input range 2.2V to 6V; bypass to ground through at least 1µF MLCC capacitor. |
| 2 | GND | power_in | Ground pin. |
| 3 | EN | input | Active-high enable input; the device turns on when EN is driven above VIH (min 1.0V) and off when below VIL (max 0.3V), and the EN pin should be tied to IN if the feature is not used. |
| 4 | NC | unconnected | No internal connection; leaving this pin floating does not affect chip functionality. |
| 5 | OUT | power_out | Regulated voltage output pin (1.8V fixed for this variant), up to 600mA; bypass to ground through 1µF MLCC capacitor. |
