GR7130S

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

GR7130S 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); the datasheet gives no separate electrical limit for this pin.
2 VOUT power_out Chip output terminal (芯片输出端); for the GR7130 (3.0 V, ±3%) the output is 2.91-3.09 V at VIN=5 V and IOUT=1 mA, with output current of at least 60 mA (100 mA typical) at VIN=5 V.
3 VIN power_in Start-up input terminal (启动输入端); the input voltage is rated up to 18 V in operation, with a 20 V absolute maximum input voltage.

CAD (KiCad official)

  • Symbol: GR7130S
  • Footprint: Package_TO_SOT_SMD:SOT-23-3
  • 3D model: SOT-23-3 (KiCad packages3D, STEP)
  • 3D model files: gr7130s-etched.step / gr7130s-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); gr7130s.step / gr7130s.glb are the bare package body.
