PJ71K33SQ from PJSEMI, in a SOT-89. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Ground reference. Common return for both input supply and regulated output. Connect to the single-point ground of the application. |
| 2 | VIN | power_in | Unregulated supply input. Absolute max 28V; recommended operating up to 24V. Bypass with a 10uF capacitor to GND close to the pin. |
| 3 | VOUT | power_out | Regulated 3.3V output (3.135V min, 3.465V max, +/-5%). Sources up to 30mA. Bypass with a 10uF capacitor to GND for stability. |
