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

GR7350 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.
2	VOUT	power_out	Regulated output pin; for GR7350 the output is 5.0 V nominal ±3% (4.85-5.15 V at VIN=6V, IOUT=40mA) and delivers at least 250 mA with VOUT ≥ 4.5V at VIN=6V.
3	VIN	power_in	Input (start-up input) pin; the input voltage is rated at 15 V maximum for regulation, with an absolute maximum input voltage of 18 V.
