CJ6330A25M

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

CJ6330A25M from Changjing, in a SOT-23-3L. 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 Regulator ground; the datasheet gives no further limit for this pin.
2 OUT power_out Regulator output; an output capacitor must be placed between OUT and GND to maintain stability, placed as close as possible to the OUT and GND pins for best transient response.
3 IN power_in Input to the device, rated 2.5 V to 18 V; place the recommended input capacitor as close to the IN and GND pins as possible for best transient response and minimum input impedance.

Materials and finish

As the datasheet states them (page.json metadata.appearance; the 3D model's colours follow it).

Part Material Colour / plating Datasheet says Page
contacts copper • Place the input and output capacitors as close to the pins of the device as possible; • The device is connected by copper plane and the heat sink (or back pad) of the device is fully welded with 25

CAD (KiCad official)

  • Symbol: CJ6330A25M
  • Footprint: Package_TO_SOT_SMD:SOT-23-3
  • 3D model: SOT-23-3L (KiCad packages3D, STEP)
  • 3D model files: cj6330a25m-etched.step / cj6330a25m-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cj6330a25m.step / cj6330a25m.glb are the bare package body.
