WL9005HS3-33 from WPMtek(Wei Pan Microelectronics), in a SOT-23-3. 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 | GND | power_in | Ground pin; the datasheet recommends a wide copper trace for both VIN and GND and to place the input capacitor as close as possible to the device. |
| 2 | VOUT | power_out | Output pin; the device sources up to 500 mA, with current limit and short-circuit protection, and requires a minimum 1 uF ceramic output capacitor. |
| 3 | VIN | power_in | Input pin; operating input voltage is 1.2 V to 6.0 V, and the absolute maximum VIN to VOUT difference is 5 V. |
