PJ73AL33SC from PJSEMI, in a SOT-23. 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 pin; the basic circuit connects input and output capacitors to a single point GND. |
| 2 | VOUT | power_out | Regulated output voltage of 3.3V (3.234V min to 3.366V max at VIN=VOUT+2.0V, IOUT=10mA), with at least 300mA output current. |
| 3 | VIN | power_in | Input voltage pin accepting up to 20V (absolute maximum supply voltage -0.3 to +22V). |
