GR5300A18M3G

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

GR5300A18M3G 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; the datasheet specifies no separate limit for this pin.
2 VOUT power_out Chip output terminal; for the GR5300A18M3G the output is 1.8 V (1.755 V to 1.845 V at VIN=5 V, IOUT=1 mA) with output current of at least 60 mA and a dropout of typically 100 mV at 1 mA.
3 VIN power_in Input terminal (datasheet label 启动输入端); the maximum input voltage is 10 V in the electrical characteristics and 12 V as the absolute maximum rating.
