GR7344-A from GR, 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 | GND | power_in | Chip ground terminal (芯片接地端) for the SOT89-3 package. |
| 2 | VIN | power_in | Input voltage pin (启动输入端); the datasheet gives a maximum input voltage of 15 V in the product selection table and an absolute maximum of 18 V. |
| 3 | VOUT | power_out | Regulated output pin (芯片输出端) that supplies the fixed output voltage, which is 4.4 V for this part with ±3% tolerance per the selection table. |
