AP7311-12WG-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, to be bypassed to ground through at least a 1µF capacitor (operating input range 2V to 6V). |
| 2 | GND | power_in | Ground. |
| 3 | EN | input | Enable input, active high; logic low below 0.4V and logic high above 1.4V, tie to IN if unused. |
| 4 | NC | unconnected | No connection on the fixed-output version (the 1.2V AP7311-12 variant). |
| 5 | OUT | power_out | Voltage output pin, to be bypassed to ground through a 1µF ceramic capacitor. |
