CJ8833

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

CJ8833 from Changjing, in a SOT-89-3L. 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.
2 IN power_in Input to the device; the input voltage range is 2.5V to 60V, and the recommended input capacitor should be placed as close to the input as possible to reduce the impedance of the input supply.
3 OUT power_out Regulator output; an output capacitor is required for stability and should be placed as close as possible to the output, with the output voltage range rated at -0.3 to 15V absolute maximum.

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 20

CAD (KiCad official)

  • Symbol: CJ8833
  • Footprint: Package_TO_SOT_SMD:SOT-89-3
  • 3D model: SOT-89-3L (KiCad packages3D, STEP)
  • 3D model files: cj8833-etched.step / cj8833-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cj8833.step / cj8833.glb are the bare package body.
