AP2112K-2.5TRG1 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 | Input voltage supply pin; the datasheet gives a supply range of 2.5 V to 6.0 V. |
| 2 | GND | power_in | Ground reference pin for the regulator. |
| 3 | EN | input | Chip enable: logic high (VIH 1.5 V to 6.0 V) turns the regulator on, and logic low (VIL 0 V to 0.4 V) shuts it down. |
| 4 | NC | unconnected | No connection; this pin is not connected internally. |
| 5 | VOUT | power_out | Regulated output voltage pin, 2.5 V for the AP2112K-2.5TRG1 variant, with 600 mA minimum output current. |
