GR · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3
GR7140S 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) of the GR71xx LDO regulator in the SOT23-3 package. |
| 2 | VOUT | power_out | Chip regulated output terminal (芯片输出端) of the GR71xx LDO; output voltage is 3.0 V to 5.0 V with ±3% tolerance per the selection table. |
| 3 | VIN | power_in | Input terminal (启动输入端) of the regulator; the maximum input voltage is 18 V in operation and 20 V absolute maximum. |
