GR7130S from GR, in a SOT-23-3. 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); the datasheet gives no separate electrical limit for this pin. |
| 2 | VOUT | power_out | Chip output terminal (芯片输出端); for the GR7130 (3.0 V, ±3%) the output is 2.91-3.09 V at VIN=5 V and IOUT=1 mA, with output current of at least 60 mA (100 mA typical) at VIN=5 V. |
| 3 | VIN | power_in | Start-up input terminal (启动输入端); the input voltage is rated up to 18 V in operation, with a 20 V absolute maximum input voltage. |
