BDJ2FA1FP3-ZTL from ROHM Semicon, in a SOT-89-3. 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 | Vo | power_out | Regulated output pin, which is 12.0V for this J2 variant with ±1% accuracy and up to 0.1A output current, and needs a 0.3µF to 1.0µF ceramic capacitor to GND. |
| 2 | GND | power_in | Ground pin that must be the lowest voltage of all IC pins under all operating conditions, and it is internally connected to the FIN heat tab. |
| 3 | Vcc | power_in | Input supply pin with a recommended range of Vo+3.0V to 25.0V and an absolute maximum rating of -0.3V to +30.0V. |
