GR7330

GR · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23

GR7330 from GR, in a SOT-23. 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).
2 VOUT power_out Chip regulated output terminal (芯片输出端); the datasheet gives the GR7330 output as 3.0 V typical (2.91 V to 3.09 V at VIN=4 V, IOUT=40 mA).
3 VIN power_in Input terminal (datasheet label 启动输入端); maximum input voltage is 15 V in the electrical characteristics, and the absolute maximum input voltage is 18 V.
