WL9002P3-33 from WPMtek Wei Pan Microelectronics, in a SOT-89-3L. 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 reference pin; the input and output capacitor ground returns must go back to this pin through as wide and short a copper trace as practical. |
| 2 | VIN | power_in | Power input with an operating range of 2.0 V to 6.0 V and an absolute maximum of -0.3 V to 6.5 V; a ≥1 µF ceramic capacitor should be placed as close to the device as possible. |
| 3 | VOUT | power_out | Regulated output with a 1.2 V to 3.6 V output range and an absolute maximum of -0.3 V to 5 V; a ≥1 µF ceramic output capacitor (X7R or X5R) should be placed as close as possible to VOUT and GND. |
