GR7150S

GR · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-3

GR7150S 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; the datasheet gives no additional electrical limits for this pin.
2 VOUT power_out Chip output terminal; for GR7150 the output is 5.0 V (4.85 V to 5.15 V) with a minimum output current of 60 mA (100 mA typical) at VIN = 7 V.
3 VIN power_in Input terminal (labelled 启动输入端 in the datasheet); the maximum input voltage is 18 V in the electrical characteristics, and the absolute maximum rating is 20 V.
