PJ75CL33SC from PJSEMI, in a SOT-23-3. 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 for the regulator. |
| 2 | VOUT | power_out | Regulated output voltage (3.0V to 12V fixed options), which requires a minimum 1uF capacitor from VOUT to ground for stability. |
| 3 | VIN | power_in | Power input with a 3V to 40V supply range, which must stay above VOUT by the dropout voltage for the device to regulate. |
