PJSEMI · Linear Voltage Regulators (LDO) · TO-252
PJ78M05TE from PJSEMI, in a TO-252. 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 | VIN | power_in | Input voltage pin, rated up to 35 V per the absolute maximum ratings. |
| 2 | GND | power_in | Ground pin; the datasheet gives no separate electrical limit for this pin. |
| 3 | VOUT | power_out | Regulated 5 V output, rated up to 500 mA with internal thermal overload and short-circuit current limiting. |
