GR7140S

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.
