PJ78M09TE from PJSEMI, in a TO-252. 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 | IN | power_in | Unregulated positive supply input. Accepts up to 35V absolute maximum; a 0.33μF ceramic bypass capacitor to GND is recommended close to the pin for stability. |
| 2 | GND | power_in | Ground/common reference for both input and output. Also connected to the exposed tab of the TO-252 package for thermal dissipation. |
| 3 | OUT | power_out | Regulated +9V output, capable of up to 0.5A (typ. 350mA test condition). Requires a 0.1μF ceramic bypass capacitor to GND for transient response; typical short-circuit current is 50mA. |
