CJ6109A33P from Changjing, 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 | VSS | power_in | Ground reference pin; all voltages are referenced to network ground. |
| 2 | VIN | power_in | Power input; recommended supply voltage range is 1.6V to 6.0V, with a 4.7μF or larger input capacitor. |
| 3 | VOUT | power_out | Regulated output; guaranteed output current is 1.0A typical and output voltage is 3.3V for this A33 variant, with a 4.7μF or larger output capacitor. |
