GR7333

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

GR7333 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 gives no further electrical limit for this pin.
2 VOUT power_out Chip regulated output terminal; for the GR7333 the output is 3.3 V typ (±3%) with at least 250 mA output current at VIN = 4.3 V and VOUT ≥ 2.97 V.
3 VIN power_in Input (start-up input) terminal; VIN input voltage is rated up to 15 V, with an absolute maximum input voltage of 18 V.

CAD (KiCad official)

  • Symbol: GR7333
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: gr7333-etched.step / gr7333-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); gr7333.step / gr7333.glb are the bare package body.
