TD1507TR

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

TD1507TR 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). Connect a bulk input capacitor close to this pin.
2 Output output Switching output from the internal high-side power transistor. Drives the external inductor/catch-diode node of the buck converter. Absolute max -0.3V to Vin+0.3V.
3 GND power_in Device ground return. Also serves as the thermal path via the TO252-5L tab (θJC ≈ 10 °C/W).
4 FB input Output voltage feedback input to the internal error amplifier. Regulated against the 1.235V internal reference; on the fixed 5V version this pin is tied through the internal divider. Feedback bias current is typically 10 nA.
5 ON/OFF input TTL-compatible shutdown input. Regulator is enabled (ON) when this pin is low or left floating (VIL ≤ 1.3V typ), and shuts down (OFF) when driven high (VIH ≥ 1.3V typ, 2.0V min). Standby quiescent current ≈ 80 µA at Vin=36V. Absolute max -0.3V to Vin+0.3V.

  • Footprint: Package_TO_SOT_SMD:TO-252-5_TabPin6
  • 3D model: TO-252-5 (KiCad packages3D, STEP)
  • 3D model files: td1507tr-etched.step / td1507tr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); td1507tr.step / td1507tr.glb are the bare package body.

Provenance

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

  • Datasheet: Techcode Semicon datasheet (16 pp, sha256 606abcd595801ad9, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
