TLV1117LV33DCYR

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223

TLV1117LV33DCYR from Texas Instruments, in a SOT-223. 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 GND power_in Ground pin. Device reference return; connect to system ground. Note that the pinout labels this pin as GND for the fixed-voltage TLV1117LV33 (Figure 1/Pin Configurations shows 'ADJ/GND' as the family label because the LV series also covers adjustable variants; for the fixed 3.3-V DCY device this pin is GND).
2 OUT power_out Regulated 3.3-V output pin. Delivers up to 1 A with 455 mV typical dropout at 1 A. Requires an output capacitor (1.0 µF typical, stable with 0-Ω ESR ceramic). The SOT-223 tab is internally connected to OUT and should be soldered to a copper pour for thermal dissipation.
3 IN power_in Unregulated input voltage pin. Operating range 2.0 V to 5.5 V (absolute maximum 6.0 V). Recommended input decoupling per Input and Output Capacitor Requirements in the Application Information section.
Tab OUT power_out SOT-223 thermal tab, internally tied to OUT (pin 2). Solder to a copper plane to reduce θJA (62.9 °C/W on high-K JEDEC board) and to carry output current.

CAD (KiCad official)

  • Symbol: TLV1117LV33DCYR
  • Footprint: Package_TO_SOT_SMD:SOT-223-3_TabPin2
  • 3D model: SOT-223 (KiCad packages3D, STEP)
  • 3D model files: tlv1117lv33dcyr-etched.step / tlv1117lv33dcyr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tlv1117lv33dcyr.step / tlv1117lv33dcyr.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
tlv1117lv33dcyr.step 64 KB You want the bare part, or you mark your own boards.
tlv1117lv33dcyr-etched.step 2.0 MB You want the part with TLV1117LV33DCYR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 506 faces against 75 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
