WL9005HS3-18 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 1 uF input and output ceramic capacitors must be placed close to the device and returned to GND with wide copper traces. |
| 2 | VOUT | power_out | Output pin rated for VOUT to GND of -0.3 V to 5 V, sourcing up to 500 mA of output current, with a minimum 1 uF X5R or X7R output capacitor required. |
| 3 | VIN | power_in | Input pin with an operating input voltage of 1.2 V to 6.0 V and a VIN to GND absolute maximum of -0.3 V to 6 V. |
