APW7137BI-TRG from Anpec Elec, 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 | LX | output | Switch pin that connects to the inductor and the external Schottky diode; the datasheet rates LX-to-GND at -0.3 to 40 V (absolute maximum) and -0.3 to 36 V (recommended). |
| 2 | GND | power_in | Power and signal ground pin. |
| 3 | FB | input | Feedback input that regulates the output at 1.23 V through an external resistor divider, which sets VOUT from VIN up to 30 V. |
| 4 | EN | input | Enable input: forcing above 1.0 V enables the device and forcing below 0.4 V shuts it down to under 1 µA supply current; it must not be left floating. |
| 5 | VIN | power_in | Main supply pin, operating from 2.5 V to 6 V, that must be closely decoupled to GND with a 2.2 µF or greater ceramic capacitor. |
