CJ75L033S

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

CJ75L033S 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 3.3V output, up to 300 mA. Requires an output capacitor between OUT and GND, placed as close to the pin as possible for best transient response.
2 GND power_in Regulator ground reference. On SOT-89 this pin is fused to the die-pad tab and should be tied to a large ground copper for thermal dissipation.
3 IN power_in Unregulated input supply, 2.5V to 36V. Place a 1µF (or larger) input capacitor as close as possible to IN and GND to minimize input impedance and improve transient response.

CAD (KiCad official)

  • Symbol: CJ75L033S
  • Footprint: Package_TO_SOT_SMD:SOT-89-3
  • 3D model: SOT-89-3L (KiCad packages3D, STEP)
  • 3D model files: cj75l033s-etched.step / cj75l033s-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cj75l033s.step / cj75l033s.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Changjing datasheet (36 pp, sha256 c4e87b13b4aa0863, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
