GR7133

GR · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-89-3

GR7133 from GR, in a SOT-89-3. 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 separate electrical limit for this pin.
2 VIN power_in Input terminal for the regulator; the GR7133 input voltage is specified up to 18 V, with an absolute maximum input voltage of 20 V.
3 VOUT power_out Regulated output terminal; the GR7133 output is 3.3 V nominal (3.201 V to 3.399 V at VIN=5 V, IOUT=1 mA) with output current of at least 60 mA (100 mA typical) at VIN=5.5 V.

CAD (KiCad official)

  • Symbol: GR7133
  • Footprint: Package_TO_SOT_SMD:SOT-89-3
  • 3D model: SOT-89-3 (KiCad packages3D, STEP)
  • 3D model files: gr7133-etched.step / gr7133-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); gr7133.step / gr7133.glb are the bare package body.
