CL9901A28S3M

ChipLink Tech · Linear Voltage Regulators (LDO) · SOT-23

CL9901A28S3M from ChipLink Tech, in a SOT-23. 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 Ground terminal (接地端) of the CL9901 regulator, pin 1 in the SOT-23 package.
2 VOUT power_out Regulator output pin; the datasheet limits VOUT pin voltage to GND-0.3 V to VIN+0.3 V and output current to 500 mA, with the output current derived as Pd/(VIN-VOUT).
3 VIN power_in Power supply input pin; the datasheet rates the VIN pin voltage at -0.3 V to +6.0 V and specifies input voltage up to 6.0 V.

CAD (KiCad official)

  • Symbol: CL9901A28S3M
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: cl9901a28s3m-etched.step / cl9901a28s3m-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cl9901a28s3m.step / cl9901a28s3m.glb are the bare package body.
