WL9005HS5-15 from WPMtek Wei Pan Microelectronics, in a SOT-23-5L. 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 pin; operating input voltage is 1.2 V to 6.0 V, with a 1 µF ceramic capacitor recommended close to the device between VIN and GND. |
| 2 | GND | power_in | Ground pin, which serves as the return for the input and output capacitors and should be connected with a wide copper trace. |
| 3 | EN | input | Enable pin; a level of at least 0.83 V enables the regulator and a level of 0.78 V or lower puts it in shutdown. |
| 4 | NC | unconnected | No connection. |
| 5 | VOUT | power_out | Output pin, which sources up to 500 mA with a fixed output voltage; a minimum 1 µF ceramic output capacitor (X5R or X7R) is required for stability and should be placed as close as possible to VOUT and GND. |
