CJ78L06

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

CJ78L06 from Changjing, in a SOT-89-3L. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OUT power_out Regulated +6 V output (5.7-6.3 V over line/load/temperature). Sources up to 100 mA. A 0.1 uF ceramic bypass capacitor to GND, mounted close to the pin, is recommended for stability and transient response.
2 GND power_in Common ground reference for the input and output. Also the SOT-89 heat-slug tab pin providing the thermal path to the PCB copper.
3 IN power_in Unregulated input, absolute maximum 30 V. Must be at least ~1.7 V above VOUT (typical dropout at 25 C) for regulation. A 0.33 uF ceramic input capacitor to GND, mounted close to the pin, is recommended.

CAD (KiCad official)

  • Symbol: CJ78L06
  • Footprint: Package_TO_SOT_SMD:SOT-89-3
  • 3D model: SOT-89-3L (KiCad packages3D, STEP)
  • 3D model files: cj78l06-etched.step / cj78l06-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cj78l06.step / cj78l06.glb are the bare package body.
