PJ73HM50SC 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; the datasheet lists it only as 'Ground' with no electrical limits. |
| 2 | VOUT | power_out | Regulated output of the 5.0V (PJ73HM50SC) version, rated for 500mA within the package power dissipation limit, with an absolute maximum of -0.3V to 6V on this pin. |
| 3 | VIN | power_in | Power input with a 3V to 20V supply range and an absolute maximum of -0.3V to 25V. |
