AP2139AK-3.0TRG1 from Diodes Incorporated, in a SOT-23-5. 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, 2.5V to 6.0V recommended operating range (6.6V absolute maximum), requires a 1µF input capacitor. |
| 2 | GND | power_in | Ground. |
| 3 | CE | input | Active high enable input; logic high (VIH min 1.2V) enables the output, logic low (VIL max 0.3V) puts the device in shutdown. |
| 4 | NC | unconnected | No connection. |
| 5 | VOUT | power_out | Regulated output voltage (3.0V fixed for this variant), up to 250mA, requires more than 1µF output capacitance with ESR 0.01Ω to 100Ω. |
