LN2401-TP

TECH PUBLIC · LED Drivers · SOT-23-5

LN2401-TP from TECH PUBLIC, in a SOT-23-5. 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 EN input Chip enable: drive EN above 1.5V to turn the part on and below 0.4V to turn it off; do not leave EN floating.
2 GND power_in Ground.
3 LX output Power switch output, the switch node connection to the inductor.
4 VIN power_in Power supply input (2.5V to 5.5V), which must be closely decoupled to GND with a 4.7µF or greater ceramic capacitor.
5 FB input Feedback pin: a resistor connected between FB and GND programs the LED current, with a threshold voltage of 0.1V.

CAD (KiCad official)

  • Symbol: LN2401-TP
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: ln2401-tp-etched.step / ln2401-tp-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ln2401-tp.step / ln2401-tp.glb are the bare package body.
