CJ6205B25M

Changjing · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-23-5L

CJ6205B25M from Changjing, in a SOT-23-5L. 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 VIN power_in Unregulated positive power input. Operating range 2.0 V to 6.0 V; absolute max VSS-0.3 V to VSS+7 V. Bypass to VSS with 1 uF ceramic close to the pin.
2 VSS power_in Device ground / negative supply return. Common reference for VIN, VOUT and CE.
3 CE input TTL chip-enable input. High enables the regulator (VCE-H min 1.5 V, up to VIN); Low shuts it down (VCE-L max 0.3 V, ISTBY <=0.1 uA). On the 'B' variant an internal pull-down holds the part off if CE is left floating and a COUT discharge resistor pulls VOUT down when disabled.
4 NC unconnected No internal connection. Leave floating or tie to VSS.
5 VOUT power_out Regulated 2.5 V output (accuracy typ. +/-2%, VOUT0.98 to VOUT1.02). 500 mA typ output current, 100 mA short-circuit current limit. Requires 1 uF ceramic load cap; typical dropout 150 mV @150 mA.

  • 3D model: SOT-23-5L (KiCad packages3D, STEP)
  • 3D model files: cj6205b25m-etched.step / cj6205b25m-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cj6205b25m.step / cj6205b25m.glb are the bare package body.

Provenance

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

  • Datasheet: Changjing datasheet (13 pp, sha256 44b90cefa78b2962, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
