GR7336-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 GR73xx LDO regulator in the SOT89-3 package. |
| 2 | VIN | power_in | Start-up/input terminal (启动输入端); the datasheet rates the input voltage up to 15 V, with an absolute maximum input voltage of 18 V. |
| 3 | VOUT | power_out | Chip output terminal (芯片输出端) providing the regulated output voltage, which is 3.6 V with ±3% tolerance for GR7336-A. |
