WL9015S3-33 from WPMtek Wei Pan Microelectronics, in a SOT-23. 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 of the LDO, which the input and output capacitors must return to through as wide and short a copper trace as practical. |
| 2 | VOUT | power_out | Regulated output voltage, specified for a 1.8 V to 5.0 V output range with an absolute maximum of -0.3 V to 6.0 V, and requiring an output capacitor of at least 1 µF placed close to VOUT and GND. |
| 3 | VIN | power_in | Power input, with an absolute maximum range of -0.3 V to 24 V and a recommended input voltage of 2.5 V to 12 V, decoupled by a ceramic capacitor of at least 1 µF placed close to the device. |
