TMI3108

TMI · DC-DC Converters · SOT-23-5

TMI3108 from TMI, 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 pin: drive EN above 1.5V to turn the part on and below 0.3V to turn it off, and do not leave it floating.
2 GND power_in Ground pin for the device.
3 LX output Power switch output and switch node connection to the inductor.
4 VIN power_in Power supply input (2.5V to 5.5V recommended range) that must be closely decoupled to GND with a 4.7µF or greater ceramic capacitor.
5 FB input Output voltage feedback pin used to set the regulated output voltage through the external resistor divider.

  • Symbol: TMI3108
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: tmi3108-etched.step / tmi3108-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tmi3108.step / tmi3108.glb are the bare package body.
