TD1507T5

Techcode Semicon · DC-DC Converters · TO-252-5

TD1507T5 from Techcode Semicon, in a TO-252-5. 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 Input supply voltage. Operating range 3.6V to 45V (absolute max 45V). Bypass with a low-ESR input capacitor close to the pin.
2 Output output Switching output from the internal NPN power transistor (emitter). Connects to the external catch diode and inductor of the buck converter. Delivers up to 3A load current.
3 GND power_in Device ground reference for all internal circuitry and the switching return path.
4 FB input Output voltage feedback input to the internal error amplifier. For the fixed 5V version this pin ties directly to the regulated output; internal reference is 1.235V. Typical feedback bias current 10nA.
5 ON/OFF input TTL-compatible shutdown control. Regulator is ON when the pin is low (<0.6V typ) or left floating; regulator is OFF (standby, IQ ~80uA) when driven high (>2.0V). Absolute max -0.3V to Vin+0.3V.

CAD (KiCad official)

  • Symbol: TD1507T5
  • Footprint: Package_TO_SOT_SMD:TO-252-5_TabPin6
  • 3D model: TO-252-5 (KiCad packages3D, STEP)
  • 3D model files: td1507t5-etched.step / td1507t5-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); td1507t5.step / td1507t5.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
td1507t5.step 196 KB You want the bare part, or you mark your own boards.
td1507t5-etched.step 1.6 MB You want the part with TD1507T5 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 434 faces against 139 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
