WL9005HS5-28 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; the operating input voltage range is 1.2V to 6.0V and VIN to GND is rated -0.3V to 6V. |
| 2 | GND | power_in | Ground pin, the reference for the VIN (-0.3V to 6V), VOUT (-0.3V to 5V) and EN (-0.3V to 6V) ratings to GND. |
| 3 | EN | input | Enable pin; EN high is 0.83V minimum to enable the output and EN low is 0.78V maximum to shut it down. |
| 4 | NC | unconnected | No connection; the datasheet assigns no electrical function to this pin. |
| 5 | VOUT | power_out | Output pin; fixed output voltage with output current up to 500mA, and VOUT to GND is rated -0.3V to 5V. |
