TPS715345DCKR

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SC-70-5

TPS715345DCKR from Texas Instruments, in a SC-70-5. 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 NC unconnected No connection on the fixed-output TPS715xx variants (this pin is FB only on the adjustable TPS71501). For TPS715345 leave floating or tie as convenient.
2 GND power_in Device ground reference. All voltage measurements are referenced to this network ground terminal.
3 NC unconnected No internal connection. Leave floating or tie as convenient for layout.
4 IN power_in Unregulated input supply, 2.5 V to 24 V (absolute max 24 V, -0.3 V min). Bypass with a ≥ 0.047-µF (typ) input capacitor close to the pin.
5 OUT power_out Regulated 3.45-V output, 50-mA rated (internally current limited). Requires an output capacitor ≥ 0.47 µF for stability; stable with any capacitor type in that range.

Two STEP files. Same geometry, different body top:

File Size Use it when
tps715345dckr.step 87 KB You want the bare part, or you mark your own boards.
tps715345dckr-etched.step 2.4 MB You want the part with TPS715345DCKR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 583 faces against 102 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.

Provenance

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

  • Datasheet: Texas Instruments datasheet (22 pp, sha256 a7e71ad1fef999bc, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
